The Differences Between HTML, XHTML and HTML5

HTML is a markup language, which allows developers to represent text data in a formatted way using tags. There are many different versions of this markup language and most of them are widely used for web design.

The most popular one is HTML5. It has a lot of new features that improve the functionality of websites.


Many people who are new to web design are confused about the differences between HTML, XHTML and HTML5. All of them are markup languages, but there are some differences. XHTML is more structured than HTML, and requires that tags be properly closed and in lowercase. It also requires a Document Type Declaration, which HTML does not require.

While XHTML is more strict, it does not have the flexibility of HTML5. This makes it difficult for some developers to use XHTML in their projects. In addition, XHTML does not support a number of features that are common in HTML5. For example, it cannot create a list of items that is numbered or contains li> elements.

HTML5 is the latest version of the HTML markup language, and it includes a number of new features that make it more flexible than previous versions. For example, it supports a form of data storage called web storage. This allows you to store content offline, and it also provides support for drag-and-drop functionality. It also has improved support for rich media elements.

There are a number of benefits to using HTML5. It can improve your website’s search engine optimization by making it more accessible to search engines. It can also be used to create fancier forms, which are important for websites that require users to enter information.

Moreover, it can be used to create dynamic content and is compatible with most devices. It also has advanced functionality that can be used to add social media buttons, full-screen browsing for IOS users and more.

In addition, XHTML is more streamlined than HTML5. This makes it easier to debug and maintain. However, it is not recommended for novices because it can be more difficult to learn than HTML5. In addition, some older browsers may not support all of the features in XHTML. XHTML can also be more difficult to debug because it uses stricter syntax than HTML5. However, it is worth the effort, especially for experienced web designers.


HTML is a markup language that allows developers to create web pages. It uses tags to define the structure of a document and to identify what elements should be displayed. It also includes a set of attributes to define the behavior of the tags. For example, the href> tag specifies where to link to a document.

HTML5 is the latest version of the HTML markup language and has some major changes. The new features allow developers to create more dynamic websites. For example, it includes support for drag-and-drop and offline storage. It also provides a number of APIs for events such as form submission and geolocation. However, it is important to note that older browsers may not support all of the new features in HTML5.

The biggest difference between XHTML and HTML is that XHTML has stricter structure rules than HTML. For example, XHTML requires all attribute values to be quoted. In addition, it has different requirements for the DOCTYPE declaration. XHTML also requires lowercase tags and a separate element for header information. HTML, on the other hand, is more forgiving and does not require lowercase tags or a separate element for header information.

While XHTML is less forgiving than HTML, it has some advantages over HTML5. For example, it supports a wider range of browsers. It also supports semantic markup, which makes it easier for search engines and screen readers to understand the content of a page. In addition, it has support for forms and JavaScript.
