Consistent Error Handling

“Tag soup” is one of the biggest problems in HTML documents. It is structurally improper HTML code. Every browser has its own parser to check “Tag soup” for HTML documents. New browser vendors use reverse-engineering, to create an error handling process, to test malformed HTML documents in other browsers.

According to stats about 90% of web pages have syntactically incorrect HTML code that’s why error handling is important. The error handling helps developers and save their time while writing the code. HTML5 is attempting to find out and codify this error handling.

Support for More Web Application Features

HTML5 is developed to give developers more control to make the websites more like an application. It allows the developers to use many functions which were only achieved by flash or JavaScript code. Now there are many features that come with HTML5 and you don’t have to use flash or JavaScript.

Enhanced Element Semantics

One of the big advantages of HTML5 is its enhanced element semantics. The new tags are introduced such like header, footer, nav, section, article etc. made the error handling process less painful.

Mobile phones are the most important part of website development in these days. If you have a website that is not mobile friendly you are going to lose a big amount of viewer for sure. HTML5 gives websites the mobile friendly look and feel to give the users to use the websites even from their mobile phone or tablet with same effect.

Support for Custom Data Attributes

When you say HTML vs HTML5 custom data attributes is one of the big differences between the two. In HTML4 if you use custom attribute in a tag you will end up in browsers rendering the document in a quirks mode. But the data-* attribute has solved the custom attribute problem in HTML. The data-* attribute allow the developers to store and use data as a simple string. It helps in reducing server side queries.

No More Cookies Thanks to Local Storage

HTML5 local storage is another big feature that developers love to use. It replaced the cookies as they are not as convenient as local storage. Cookies can store limited information and users can turn them on or off. But on the other, stateless nature of the HTTP protocol can be used with HTML5’s local storage object.

The local storage object can be accessed within a script at anytime because it is included in global window namespace. It can hold only the string values, but with the help of JSON.parse() and JSON.stringify() methods serialization is quite easy. It has a sessionStorage as well that can hold value for a user session.

Form Field Autofocus

There are many form field features HTML5 has brought in. The autofocus attribute is used to set auto focus of a document when it loads. The user can change the focus of a field, it just place the cursor where you want when a page loads.

Form Field Watermark (Placeholder)

HTML5 has another very useful attribute called “placeholder attribute”. It is used in a input box and it specifies a short hint that tells about the value of an input field. The short hint is put on view in the input field prior to the user enters a value.

Script and Link Tags No Longer Require Type Attribute

The “type attribute” of <link> and <script> tag has been removed as the link tag is used only for external CSS file and script tags are used for external JavaScript files.

HTML5 Canvas Element

HTML5 has an amazing new element called <canvas>. It is used to draw graphics using JavaScript. It is just a container that holds the graphics and JavaScript is used to draw graphics in it. There are many ways to draw shapes like boxes, circles, paths, add images and even text.
