HTML in Visual Studio Code
Everybody is using it. It's being heralded as the savior of the Internet, allowing people to create rich, engaging web pages without resorting to using Flash and Shockwave. Well, that's not an easy question to answer. In this HTML5 tutorial, we'll try to provide some answers. HTML5 is used to describe a really diverse group of things. It's a standard of writing web pages.
It's a collection of APIs. It's a new way of adding interactivity to web pages. Perhaps you've created your own Wordpress theme, or edited a MySpace layout back in the day. The point is, I'm assuming that you know your way around a web page and that what we discuss in this guide won't be too alien to you. The aim of this guide is not to teach you the entirety of HTML5.
That would be entirely out of the scope of this book. The aim is to provide a gentle introduction to these amazing new web technologies, and to show you some cool ways of incorporating them into your websites. It's a fair question. In a world of smartphones and apps, is it really important to learn how to program web pages?
Well, believe it or not, it's really common to write smartphone applications using HTML5 technologies. Blackberry is another major company that is immensely keen on HTML5.
This is obvious in the latest iteration of their mobile operating system, Blackberry OS 10, where they are actively encouraging developers to develop applications for their phones using web technologies.
A working knowledge of HTML5 is essential in today's smartphone climate. In addition, learning HTML5 is good for your career. Don't believe me? According to Indeed. With more and more companies changing their websites to use HTML5 technologies, developers who know the HTML5 stack are sought after — now more than ever. This HTML5 tutorial assumes a couple of things.
Firstly, it presupposes that you know how the web works, and that you know how to create a basic web page. You should be able to cobble some HTML elements together and to be able to present some information in a web browser.
Secondly, this guide assumes you know what CSS is and how it works. We don't expect you to be design geniuses, nor are you expected to know the entire CSS specification off the back of your hand. You should, however, be able to apply styling to an element on a web page, be able to link to a CSS file and know the different between an ID and a class and how to apply styling to each of them. If you're scratching your head at the above, don't worry.
You're also going to need a modern text editor and browser. Any version of Internet Explorer that is older than IE 9 and some older versions of Safari, Chrome and Firefox will struggle with many features that are part of HTML5 and may prevent you from following this guide. As a result, you're encouraged to download a modern browser. I recommend Google Chrome, and I will be using it in each example.
Your text editor is what you're going to use to write your code. You may be wondering what a text editor is. Well, firstly it is not a word processor. Programs such as Microsoft Word and Apple's Pages are totally unsuited to web development. A text editor shoots out characters into a text file, and not much else. This allows you to create files that have no extra formatting, and can be saved with any extension of your choosing.
Your computer already comes with one. If you're using a Windows PC, then Notepad is the text editor that you've likely got installed. On a Mac, the situation is slightly different. OS X happens to come with four different text editors. These are called Vim, Emacs, Pico and Nano. However, unlike Notepad, all of them happen to work in the terminal. This is a little bit intimidating for people who are new to web development and should not be used by people who are new to software development.
We won't be using them in this guide. However, when you get a bit more confident with software and web development, it's definitely worth having a look at Vim and Emacs. They are both powerful text editors, and when mastered can save you an awful lot of time. On Linux, the default text editor varies between distributions.
On Ubuntu, it is likely Gedit , which is a rather pleasant text editor that is not too dissimilar from Notepad. The first is Sublime Text 2. I honestly cannot recommend this highly enough.
It comes with all the things that makes life easier for a beginning developer. Firstly, it'll make your code easier to read by coloring certain parts. Secondly, it allows you to switch between files easily and to manage entire projects of files. This is ideal for switching between files, and editing multiple bits of code on the fly. The third is the Javascript console that is built into Google Chrome. This allows us to write Javascript and see it being run immediately and will be used to explain basic programming concepts.
The second is a website called Codepen. It will also allow you to see your changes instantly. In this chapter, you will learn about Semantic Markup, and how to organize your code based upon its content. These allowed you to create a group of elements and then apply styling to those elements. This worked, but there was room for improvement. Div doesn't actually mean anything, really. Semantic markup is a new feature in HTML5. It brings in new tags, which work in the same way as a 'div' tag, but are for tagging common parts of a page.
In this piece of code, we have a navigation bar, a title and a list. This isn't too dissimilar to most websites you're likely to ever go on, when you think about it. Let's have a look an article on MakeUseOf. You'll notice that there is a part of the page that is reserved entirely for navigating to other articles. You'll also notice that there's another part of the page that contains the words that constitutes an article.
Towards the top of the page, you'll see a header containing the MakeUseOf logo and some other links. When you think about it, a lot of websites follow these conventions. Most websites have a part that is reserved for navigation. They usually have a body of content. They more than likely have a header. Semantic tags are tags that allow you to define parts of a website which are commonly found on most websites.
They don't add anything to the page, but allow you to group tags based upon their content and apply stylings to those groups. As you can see, the code is much easier to read. You know which parts are which and there is no ambiguity. This is important, because it makes it easier to write good, clean code. Should you ever decide to become a professional web designer, this becomes paramount — you never know who will be reading the work that you produce.
Section is a really useful tag. It's used for grabbing huge swathes of information and content that are marked with a heading or a title. Think of this like a chapter in a book.
A chapter has a title, and may also contain pictures, diagrams, graphs and words. A section tag would be used to contain all of that. The article tag is used for what it sounds like; Containing content such as a blog post or a news story. This content should be able to be detached from the rest of the blog and still make coherent sense.
This tag is reserved for content that is related to, but not an integral part of the web page. This could be a bunch of facts that relate to a news story, or the biography of a user on a blog. Lots of web pages have a bar on the top of the page that contains a logo, some information pertaining to the site and perhaps some links. In Semantic markup, you'd use a Header tag to contain all of this. This element is reserved for the navigation part of your website. This would contain links to other websites or to other pages on the website.
Within the context of MakeUseOf, this could be the part of the page that is below the header. This tag is reserved for the bottom part of the page.
30+ Examples of HTML5 Websites
When the user enters a word in the box and clicks the button, a web API is called that returns the meanings of the word. They are displayed in an Ubuntu List. Nor does it use a Cordova API. Be sure to check out other tutorials that dive into these important areas too. Give the project any name you want.

This means that you can start creating HTML5 projects without having to perform any additional setup steps or install any additional software. While you can run your UE4 HTML5 project with bit web browser, using a bit version web browser is highly recommended. You can find bit versions of the Google Chrome and Firefox web browsers using the following links. Google Chrome 64 Bit. Firefox 64 Bit. In Firefox nightly, SharedArrayBuffer can be enabled in about:config by setting the javascript. The type of build that you create for your project depends on what you are trying to accomplish. Development builds are used when you are testing or debugging your project before you want to release it.
