Hello guys,

Currently, I’m in the process of learning how to build a website. I have built a website with HTML CSS Javascript. Right now I’m trying to learn how to make my website able to collapse into vertical navigation just like it’s shown on this website, I attached the link here so you can get an idea: https://mdbootstrap.com/snippets/jquery/mdbootstrap/911242#html-tab-view

You have the toggle menu in place but you have called it something else other than #toggle so the JS needs to change to reflect that. You called it #mobile-menu.

You haven’t actually styled the hamburger so you need to grab the styles that create the hamburger from wherever you saw that code.

Once in place you would set it to display:none by default and then use a media query at the width required to show it. At that same point in the media query you would restyle the navigation so it sits under the header as usually required.

Here’s a basic start but as you are learning I am leaving you to fill the gaps.

#mobile-menu {
  display: none;
  height: 50px;
  width: 100px;
  background: red; /* just for testing - you need to find the correct css for this*/
}

/* I've used 800px as the trigger point but this needs to change based on the design */
@media screen and (max-width: 800px) {
  #mobile-menu {
    display: block;
  }
  .nav {
    display: none;
  }
  .active + .nav {
    display: block;
  }
  /* Now from here you need to style the way you want that dropdown to look on small screen.
  This would probably be using absolute positioning to show the menu over any other content*/
  
  /* e.g. just for starters*/
  header {
    position: relative;
  }
  .nav {
    position: absolute;
    left: 0;
    top: 100%;
  }
  /* now adjust all the styling for the list elements as required*/
  /* ??? */
}
 The js is changed to reflect the correct hamburger id.

const toggle = document.getElementById("mobile-menu");
toggle.onclick = function () {
  toggle.classList.toggle("active");
};

That’s a basic start for you to get it working so all you need to do now is style it all as required:)

Thanks a lot, buddy. I really appreciate your unlimited support. You’re right. This code is left from a previous project that I forgot to delete. But just like you mentioned, I will try to figure out the rest, so the learning process will be more effective. Can I get back to you if I get stuck?

Apache:

How about the html, should I do any changes?

You might be interested in the discussion in a similar thread where I discuss using nested lists for the html.

I’ll make a few observations and then you can decide yourself whether its good to use or not.

Firstly you should get rid of the inline click handler and do it from the JS file instead.

<button onclick=”myFunction()” etc..

Add an event listener in the JS file instead.

The following JS targets one specific element by its id:

document.getElementById(“myDropdown”).classList.toggle(“show”);
That would be no use if you had multiple menu items.

This structure makes it awkward to target th…

The last example shows the difference when using a nested list. It’s not wrong to use normal html but it’s much more extensible in the nested list approach and allows for unlimited nestings more easily. There’s no need to change if you are not following that approach.

Note there is no hamburger in that example as we were only discussing the basic menu.

Apache:

Can I get back to you if I get stuck?

Of course just post if you get stuck. I am away now until Sunday afternoon but someone else will hopefully jump in before then

Hello again dear Paul,

I came back again to you again with almost the same topic. I tried by myself making my website collapse into a vertical navigation menu with both dropdown buttons on the left side when I click on the hamburger button. But I could not accomplish this step. Could you please help me with this issue?? Down here you can see a link för the style that I’m working on in example 2

I’ve copied the new code into a codepen and basically added the code I gave you in the previous answer

I’ve very roughly styled the dropdown when the hamburger is open just so you can see what to do. It isn’t meant to be a finished product as such. I wouldn’t actually use the same html as you for the dropdown but I explained that in an earlier post and I would have used a more structured list approach and a more consistent button usage.

However the demo serves as an example of how to implement the hamburger and start the styling for the dropdown.

I’ve given you the code for that so not sure what you are asking?

The css you posted doesn’t have the media query in place and you aren’t hiding the button on full screen. With the media query in place the nav is hidden and the hamburger goes to the right automatically because the nav is moved into its new position.

You seemed to have grabbed some other code for the hamburger but I suggest you use mine and style it as you wish. The hamburger code in your example looks like a checkbox hack and there should be a whole load of css that goes with it.

I suggest you work from my working code.

Apache:

Ok! What do you mean by bootstrap?

He probably means the framework you keep mentioning! Bootstrap5 is the latest version. It has components that create hamburgers and dropdowns out of the box.

However I don’t believe you are at a level where you could utilise it properly yet as it has a steep learning curve and indeed once you know how to use it you could have done without it.

How to Become a Blockchain Developer?│Tips, Salary & Jobs

News

Learn & Tools

Reports

This guide explores careers in blockchain development, the steps necessary to enter the field, and the attributes needed to become a blockchain developer. In addition, it explains how blockchain technology works and a breakdown of expected blockchain developer salaries from across the globe.

Blockchain is a transformative technology that opened up a new field of development known as Blockchain Development, which has created several job opportunities for developers and technicians. To help our readers understand better the role of a blockchain developer, let’s first explain what a blockchain is and how it works.

What is blockchain and how does it work?

A blockchain is a decentralized, distributed public ledger that operates on the internet. It’s a digital database that records data, and no one can change or corrupt the information stored therein.

Three principal technologies define the operation of a blockchain:

1. Private key cryptography: A secure code that allows crypto holders to make transactions and prove ownership of their assets;

2. Distributed network: A shared ledger that regulates data and transactions to avoid fraud and tax evasion;

3. Reward or incentive: A token is given to miners for servicing the blockchain and maintaining its security levels.

A blockchain can be public, private, permission-based, centralized, or decentralized. Each blockchain has a team, usually consisting of multiple parties that use cryptography to ensure all transactions are secure, accessible, consistent, and tamper-proof.


Crypto beginners’ corner:


Blockchain development explained

Blockchain technology has transformed how different companies process and manage data while doing business. Initially developed as a platform to support Bitcoin mining and transactions, the technology has demonstrated a level of versatility and security that has drawn governments and different business sectors to recognize and use it.

With the number of people working in the blockchain industry climbing over 80% year-on-year and the growing popularity and potential, blockchain development has opened a completely new front for career and employment. Before diving into how to become a blockchain developer, aspirants should first know who a blockchain developer is and what the job exactly involves.

Blockchain developers develop and optimize blockchain protocols, construct the architecture of blockchain systems, and develop web apps in line with blockchain technology. They also develop 3D models, 3D content, and 3D designs such as what we see in metaverse games.

Roles of a blockchain developer

To help one understand best the role of a blockchain developer, we need to ascertain that blockchain developers fall under two types: Core Blockchain Developers and Blockchain Software Developers. These are two major sub-divisions of blockchain development.

All the same, the following attributes are common to both sets of blockchain developers:

  • Solid understanding of coding language;
  • Deep understanding of blockchain technology;
  • Strong knowledge of cryptography and security principles;
  • Good knowledge of smart contracts;
  • Familiarity with algorithms and data structures;

Core Blockchain Developers

Core Blockchain Developers construct the architecture of a blockchain system, design protocols, select the design of consensus protocols, and participate in the advanced decision-making and development of blockchain technology. They also oversee the security and supervision of the entire network.

In short, Core Blockchain Developers set the foundation upon which other developers build. Their main programming languages are:

Blockchain Software Developers

Blockchain Software Developers use the core blockchain architecture built by core developers to create decentralized applications (dApps) and non-fungible tokens (NFTs) on a blockchain network. They develop smart contracts and interactive front-end designs for dApps. These blockchain professionals are also involved in backend development and supervision of the entire stack running the dApps they create.

Blockchain software developers use different programming languages for smart contracts, mobile, web, and backend applications.

Mobile 

  • React-native; 
  • Swift; 
  • Android;

Web 

  • React-native; 
  • Angular;
  • TypeScript;

Backend

Smart contract

  • Truffle; 
  • Solidity; 
  • Ember; 
  • Ether;

Overall, both sets of blockchain developers are responsible for creating innovative Web3 solutions to challenging problems using blockchain technology. For example, they develop solutions for command and control and ensure the high integrity of the entire network.

Additionally, they perform complex analyses, computer software debugging, development, and testing for specific product hardware or technical service lines of various blockchain-based businesses. 

Blockchain developers also design software, operate architecture integration, and select computer systems. Their work also involves operating on several systems and applying knowledge of one of multiple platforms and programming languages.

Steps to making a successful career as a blockchain developer

With the growing popularity of blockchain and cryptocurrency, several IT organizations and crypto-related companies are in need of professionals such as blockchain developers, blockchain engineers, blockchain administrators, and more.

So after knowing what a blockchain is and how it works, blockchain developers, and their roles, the next step is to learn how to become a blockchain developer.

There are two main routes to becoming a blockchain developer. One, you can start from scratch without any knowledge of programming. Two, you can have existing experience in careers that are related to blockchain and build upon that foundation.

Whether it’s from scratch or with existing knowledge in blockchain-related careers like information technology, data science, or computer science, there are important pillars that guide blockchain enthusiasts to launch a successful and worthwhile career as blockchain developers. The following attributes are essential to anyone aspiring to be a blockchain developer:

1. Academic excellence

Blockchain developers need a strong academic background in subjects such as mathematics, information technology, or computer science. A Bachelor’s or Master’s degree specializing in relevant topics such as cryptography or programming would provide a good start.

2. Relevant technical skills

In addition to a solid academic background, blockchain developers need a set of specific technical skills, including:

 Cryptography

Blockchain combines data structure and advanced cryptography, so blockchain developers need a clear grasp of cryptography to help them with creating asynchronous encryption, which is used to generate digital signatures. Blockchains also use different encryption methods, such as KECCAK256 or SHA256, which developers must understand how and where to apply.

Data Structures

Strong knowledge of data structures is helpful to blockchain developers in strengthening their level of understanding of the challenges they tackle at a broader level. It also helps them optimize solutions to the problems involved. Good knowledge of data structures such as arrays, trees, or linked lists also helps in the efficient organization and storage of data.

Smart contract development

Smart contracts have become part of blockchain technology since the release of Ethereum. Nearly all blockchains try to integrate smart contract functionality into their systems to facilitate the smooth application of business logic. Blockchain developers, therefore, need to have a clear grasp of smart contract development using different network-specific languages such as Viper, Solidity, or Chaincode, among others.

Programming, databases, and networking

Blockchain developers need deep knowledge of coding to help them develop various blockchain applications. Additionally, they should be conversant with the blockchain network to understand the shared data across all nodes. Both database management and computer networking are essential technical skills that blockchain developers need to create and maintain blockchain systems.

3. A basic understanding of the blockchain architecture

Video: Apple CEO Tim Cook congratulates Dubai-based Indian girl who developed iOS app when she was just 8 years old – Gulf News

Dubai: An Indian girl in Dubai who developed an iOS app for iPhones at the age of eight and has been congratulated by Apple CEO Tim Cook for her achievement at such a young age.

Meet Hana Muhammad Rafeeq, now aged 9, who introduces herself as “the youngest Apple iOS developer”. Though Gulf News could not independently verify this, Hana has pointed out online reports that indicate that her claim seems to be valid.

Moreover, the CEO of Apple himself has congratulated her in his reply to her mail in which she had explained her app and other achievements.

“I created and published an Apple mobile application at the age of eight,” Hana wrote in the email to Cook, a copy of which has now been shared with Gulf News.

10,000 lines of codes

“I got introduced to coding by the age of five and it seems I am the youngest in the world to achieve this. In addition, I almost avoided using any third-party ready-made codes, libraries, or classes in my app. I hand-wrote more than 10,000 lines of codes for this app. Please have a quick preview,” she wrote, sharing the YouTube links of her works.

Giving further details about her, Hana wrote that she is an Indian girl, born and brought up in the UAE.

“The reason for this writing is for my parents to say I did something extraordinary and let the Apple leader know how passionate [I am] in technology, especially Apple. Just to make the world aware that coding is not that impossible, instead it is an essential subject to include in early stages of child education, [with] the same priority as human communication language.

“The future is all about communication, not only between humans but also with the machines, animals, cells, microbes and planets. So the digital opportunities are never-ending, it’s just begun.

“If you feel my stories and thoughts are worth your time, please revert back or else just ignore. I really understand the value of time,” her email read.

The next morning, Hana was woken up by her parents after they saw Cook has replied to her email.

“Hana, Congratulations on all of your impressive achievements at such a young age! Keep at it and you will do amazing things in the future. Best, Tim,” read his reply.

“I was so excited to have his response as appreciation to my email,” Hana told Gulf News.

Her parents were happier as they consider the tech leader’s reply as an affirmation to the claims that she has made in her email. “They [at Apple] have the mechanism to verify the claims. There are many kids developing apps. I hope her expertise and hard work at this age stand out,” said her father Muhammad Rafeeq.

He was prouder to reveal that Hana’s instructor in coding is her elder sister, 10-year-old Leena Fathima.

How they learned coding

The sisters have been largely homeschooled by their parents, especially for the last four years. Explaining how they got into coding, Leena said it all had started when their father, a project management consultant, was busy coming up with an edutech company and asked their mother Fathimath Thahira, who had done BCom with computer applications, to learn coding to help him with his startup.

“While my mama was learning coding, I popped my head into the screen. I started coding at the age of five and I developed a website at the age of six when I was familiar with HTML and CSS. The website’s name is lehanas.”

On her website, Leena introduced fruits, vegetables and animals for kids and also supported the flood relief efforts in the family’s home state Kerala by providing the link to the Chief Minister’s Distress Relief Fund.

“When I created my website, my sister also popped her head into the screen. So, at that time, I started teaching my sister how to code.”

Though their entrepreneur father’s startup dream couldn’t take off yet due to lack of funding and their mother went on to work for a fintech company, the young siblings remained enchanted by the coding languages. Implementing the learning methodologies adopted in their father’s project, they said they went on to study coding and other subjects on their own.

“We don’t have any subscriptions to any tutorials. But we used to refer the internet for documentation and videos. And we have our own knowledge gaining process set by our parents,” said Hana.

The sisters are now experts in coding languages HTML, CSS, C, C++, Swift and the latest SwiftUI. They are also learning human languages English, Spanish German, Arabic, Hindi and Malayalam.

With big dreams to change the world in their own ways, the sisters want to offer free coding classes to orphans through a foundation named after them. “When we teach one orphaned child, we want that child to teach ten other orphans in turn. Creating such a project is our dream,” said Leena.

About ‘Hanas’ app

Hana’s app on App Store is called ‘Hanas’, with a purple and pink butterfly logo. The free app contains stories for children including short stories, bedtime stories, moral stories and classic stories. “This application will help parents and children because there is an option to make audio stories, so the parents can make audio stories. When the parents are busy, the children can play those audio stories,” said Hana, who turned 9 weeks after launching the app.

She explained that she was inspired to come up with the app as she has realised that many parents do not find time to read stories for their children.

“My mom used to read out bedtime stories for us. But, nowadays we see in movies and real life that many parents are unable to do it. So, I hope they can record the stories during their free time using my app, so their children won’t miss hearing the stories from their own parents.”

Hana has added her own audio stories as well “so that the children can listen to my audio as a friend”.

“I have also made a beautiful interface with a lot of options for customising fonts,” said Hana who wishes to attend Apple’s Worldwide Developers Conference next year.
