HTML5 was designed to do just about something you need to do on-line with out having to obtain browser plugins or different software program. Want to create animations? Embed music and flicks? Build superior purposes that run in your browser? You can with HTML5.

In this submit, we’ll cowl all the pieces you want to learn about HTML5, together with:

What is HTML5?

HTML5 is the most recent model of HTML. The term refers to two things. One is the updated HTML language itself, which has new elements and attributes. The second is the larger set of technologies that work with this new version of HTML — like a new video format — and enable you to build more complex and powerful websites and apps.

To understand how HTML has evolved over the years, let’s look at the differences between HTML and HTML5.


HTML is the World Wide Web’s core markup language. Originally designed to semantically describe scientific documents, it has since evolved to describe much more.

Most pages on the web today were built using HTML4. Although much improved since the first version of HTML written in 1993, HTML4 still had its limitations. It’s biggest was if web developers or designers wanted to add content or features to their site that weren’t supported in HTML. In that case, they would have to use non-standard proprietary technologies, like Adobe Flash, which required users to install browser plugins. Even then, some users wouldn’t be able to access that content or feature. Users on iPhones and iPads, for example, wouldn’t be able to since those devices don’t support Flash.

Cue, HTML5. HTML5 was designed to cut out the need for those non-standard proprietary technologies. With this new version of HTML, you can create web applications that work offline, support high-definition video and animations, and know where you are geographically located.

To understand how HTML5 can do all that, let’s look at what’s new in this latest version of HTML.

What is new in HTML5?

HTML5 was designed with major objectives, including:

  • Making code easier to read for users and screen readers
  • Reducing the overlap between HTML, CSS, and JavaScript
  • Promoting design responsiveness and consistency across browsers
  • Supporting multimedia without the need for Flash or other plugins

Each of these objectives informed the changes in this new version of HTML. Let’s focus on seven of those changes below.

New Semantic Elements

HTML5 introduced several new semantically meaningful tags. These include <section>, <header>, <footer> <nav>, <mark>, <figure>, <aside> <figcaption>, <data>, <time>, <output>, <progress>, <meter> and <main>. These make it easier to write cleaner code that clearly delineates style from content, which is particularly important to users with assistive technologies like screen readers.

Inline SVG

Using HTML4, you’d need Flash, Silverlight, or another technology to add scalable vector graphics (SVGs) to your web pages. With HTML5, you can add vector graphics directly in HTML documents using the <svg> tag. You can also draw rectangles, circles, text, and other vector-based paths and shapes using this new element. Below is an example of a circular shape created using the SVG <circle> element.

Form Features

You can create smarter forms thanks to HTML5’s expanded form options. In addition to all the standard form input types, HTML5 offers more, including: datetime, datetime-local, date, month, week, time, number, range, email, and url. You can also add date pickers, sliders, validation, and placeholder text thanks to the new placeholder attribute, which we’ll discuss later.

WebM Video Format

Before HTML5, you needed browser plugins to embed audio and video content into web pages. Not only did HTML5 introduce <audio> and <video> tags which eliminated the need for browser plugins, it also introduced the WebM video format. This is a royalty-free video format developed by Google that provides a great compression to quality ratio. This can be used with the video element and is supported by most browsers.

Placeholder Attribute

HTML5 introduced the placeholder attribute. You can use this with the <input> element to provide a short hint to help users fill in passwords or other data entry fields. This can help you create better forms. However, it’s important to note that this attribute is not accessible to assistive technologies. Feel free to read more about the problems with the placeholder attribute.

Server-sent Events

A server-sent occasion is when an internet web page routinely will get up to date information from a server. This was attainable with HTML4, however the internet web page would have to ask

HTML5 helps one-way server-sent occasions. That means, information is repeatedly despatched from a server to the browser. Think of how helpful this may be in case your web site included inventory costs, information feeds, Twitter feeds, and so forth. Server-sent occasions had been supported within the earlier model of HTML, however the internet web page would have to repeatedly request it.

Local Web Storage

With the earlier model of HTML, information is saved regionally by way of cookies. With HTML5, internet storage is used instead of cookies thanks to a scripting API. This permits you to retailer information regionally, like cookies, however in a lot bigger portions.

Now that we perceive what’s new in HTML5, let’s check out why you ought to be utilizing it in your web site.

Why HTML5?

HTML5 affords a variety of advantages over earlier variations of HTML — a few of which we’ve talked about briefly above. Let’s take a better have a look at just some the reason why HTML5 is so particular.

It’s appropriate throughout browsers.

HTML5 is supported by all the key browsers, together with Chrome, Firefox, Safari, Opera, in addition to iOS for Chrome and Safari and Android browsers. It may even work with the older and fewer fashionable browsers like Internet Explorer. That means when constructing with HTML5, that customers could have a constant expertise in your website, it doesn’t matter what browser they use or whether or not they’re on cellular or desktop.

It allows offline searching.

HTML5 permits you to construct offline purposes. Browsers that help HTML5 offline purposes (which is most) will obtain the HTML, CSS, JavaScript, photographs, and different assets that make up the appliance and cache them regionally. Then, when the consumer tries to entry the online utility and not using a community connection, the browser will render the native copies. That means you received’t have to fear about your website not loading if the consumer loses or doesn’t have an lively web connection.

It permits you to write cleaner code.

With HTML5’s new semantic components, you possibly can create cleaner and extra descriptive code bases. Before HTML5, builders had to use numerous normal components like divs and magnificence them with CSS to show like headers or navigation menus. The outcome? A lot of divs and sophistication names that made the code tougher to learn.

HTML5 permits you to write extra semantically significant code, which allows you and different readers to separate type and content.

It’s extra accessible.

Also thanks to HTML5’s new semantic components, you possibly can create web sites and apps which can be extra accessible. Before these components, display readers couldn’t decide {that a} div with a category or ID identify “header” was truly a header. Now with the <header> and different HTML5 semantic tags, display readers can extra clearly study an HTML file and supply a greater expertise to customers who want them.

How to Use HTML5

To begin utilizing HTML5 in your web site, it’s really helpful that you simply create an HTML template first. You can then use this as a boilerplate for all of your future tasks shifting ahead. Here’s what a fundamental template appears to be like like:

<!DOCTYPE html>
<html lang=”en” manifest="/cache.appcache">
<title>This is the Title of the Page</title>
<meta charset="utf-8">
<hyperlink rel="stylesheet" rel="noopener" goal="_blank" href=""> <!-- This hyperlink is just vital for those who’re utilizing an exterior stylesheet -->
/* These type tags are solely vital for those who’re including inner CSS */
<h1>This is a Heading</h1>
<p>This is a paragraph.</p>

Let’s stroll by way of the method of constructing this file line-by-line so you possibly can create an HTML template on your internet tasks. You can comply with alongside utilizing a basic text editor like Notepad++.

  • First, declare the type of document as HTML5. To do so, you’d add the special code <!DOCTYPE html> on the very first line. There’s no need to add “5” in this declaration since HTML5 is just an evolution of previous HTML standards.
  • Next, define the root element. Since this element signals what language you’re going to write in, it’s always going to be <html> in an HTML5 doc.
  • Include a language attribute and define it in the opening tag of the HTML element. Without a language attribute, screen readers will default to the operating system’s language, which could result in mispronunciations of the title and other content on the page. Specifying the attribute will ensure screen readers can determine what language the document is in and make your website more accessible. Since we’re writing this post in English, we’ll set the file’s lang attribute to “en.”
  • Also include the manifest attribute in your opening HTML tag. This points to your application’s manifest file, which is a list of resources that your web application might need to access while it’s disconnected from the network. This makes it possible for a browser to load your site even when a user loses or doesn’t have an internet connection.
  • Create the head section of the doc by writing an opening <head> and closing </head> tag. In the head, you’ll put meta information about the page that will not be visible on the front end.
  • In the head section, name your HTML5 document. Wrap the name in <title></title> tags.
  • Below the title, add meta information that specifies the character set the browser should use when displaying the page. Generally, pages written in English use UTF-8 so add the line: <meta charset = “UTF-8“ />.
  • Below, add links to any external stylesheets you’re using. If you’re loading Bootstrap CSS onto your project, for example, it will look something like this: <link rel=”stylesheet” rel=”noopener” target=”_blank” href=””>. For the sake of this demo, I’ll include a dummy link and a comment in HTML noting that it’s optional.
  • Now create the body section of the doc by writing an opening <body> and closing </body> tag. The body section contains all the information that will be visible on the front end, like your paragraphs, images, and links.
  • In the body section, add a header and paragraph. You’ll write out the heading name and wrap it in <h1></h1> tags, and write out the paragraph and wrap it in <p></p> tags.
  • Lastly, don’t forget the closing tag of the html element.

When you’re done, you can save your file with the .html extension and load it into a browser to see how it looks.

To perceive why the specification course of spanned over a decade, let’s have a look at the difficult historical past of HTML5.

In 1999, the 12 months after HTML4 was launched, the W3C determined to cease engaged on HTML and as an alternative concentrate on growing an XML-based equal referred to as XHTML. Four years later, there was a renewed curiosity in evolving HTML as folks started to understand the deployment of XML relied completely on new applied sciences like RSS.

In 2004, Mozilla and Opera proposed that HTML ought to proceed to be advanced at a W3C workshop. When the W3C members rejected the proposal in favor of constant to develop XML-based replacements, Mozilla and Opera — joined by Apple — launched the Web Hypertext Application Technology Working Group (WHATWG) to proceed evolving HTML.

In 2006, the W3C reversed course and indicated they had been all for collaborating within the growth of the HTML5 specification. A 12 months later, a bunch was fashioned to work with the WHATWG. These two teams labored collectively for various years till 2011, after they determined that they had two separate objectives. While the W3C needed to publish a completed model of HTML5, the WHATWG needed to publish and repeatedly keep a dwelling customary for HTML.

In 2014, the W3C printed their “final” model of HTML5 and the WHATWG continued to keep a “living” model on their website. These two paperwork merged in 2019, when the W3C and WHATWG signed an agreement to collaborate on the event of a single model of HTML shifting ahead.

  • ✓ Fully supported
  • ≈ Partially supported
  • ✗ Not supported
  Chrome opera Firefox safari Internet explorer
New semantic components

HTML5 is the Future of the World Wide Web

With its new semantic components, expanded kind choices, format-independent video tag, and extra, HTML5 is revolutionizing how builders construct internet pages. This, in flip, is altering customers’ experiences on-line. We can now watch movies with out being requested to replace Flash or obtain one other software program. We can use purposes after we don’t have an web connection. We can have the identical nice expertise on a website whether or not utilizing a cellphone, pill, or Smart TV — and extra.
