What is XHTML?

XHTML is a markup language written in XML; more of an XHTML is an application of XML. It is a hybrid technology between HTML and XML that combines both functionalities to become powerful and efficient. You must have heard of the term XHTML in web development. Many technologies are available today; each has its importance and use. Similarly, it has a unique role in front-end or web development. This article will try to understand XHTML from all significant aspects. We will try to understand XHTML by answering some interesting questions.

Extensible HyperText Markup Language is the name for which XHTML stands for. In a few words, it is a combination of HTML and XML. HTML serves as the medium for presenting data, whereas XML is utilized for data transportation. The World Wide Web Consortium (W3C), an international organization responsible for establishing standards for the World Wide Web (WWW), developed XHTML. It was designed to help web developers to make the transition from HTML to XML. It is designed explicitly for net device displays.

Understanding

Normal HTML works in most browsers, even if it has bad markup. Today, many browsers are available in the market, including smaller devices, mobiles, etc. They lack the power to interpret bad HTML. The solution to this was to mark up HTML correctly. XML makes restrictions to markup documents precisely and makes them well-formed, i.e., XML is more severe than HTML. That’s why HTML is combined with XML to develop XHTML with
strengths of both. Now the browsers can read and interpret markup with great accuracy. In addition, it enhances compatibility with other data formats.

How can you use XHTML?

It is the follow-on version of HTML, which means we can do everything HTML can do using XHTML. Mobile website development utilizes XHTML as it facilitates easy viewing of websites in mobile browsers. We can define and use our tags and elements in XHTML. We can convert an existing available HTML document into an XHTML document with a few changes.

Advantages and Disadvantages

The following points can be considered to make it easy when choosing to use XHTML.

Advantages

Below are the advantages:

1. Extensibility: As we can define and use our own tags, we can implement new ideas as web communication and presentation logic emerge. Let’s say there is a new program at receiving end, and we want to communicate with it; we can define our markup as per its needs and use it without any compatibility issues. New things can happen on the website as early as they emerge. Specific sets of extensions for XHTML are provided for mathematical
extensions, multimedia applications, and vector graphics.

2. Portability: As it follows the standards of XML, processing becomes easy for XML parsers. By utilizing it, we can simplify web pages, enabling small devices to handle them more effectively. This is important regarding mobile devices and small devices that contain small processors with less power. A portable advantage means we can develop a document per the specific requirement whenever needed.

3. Easy to Maintain: The error margin is less because the rules are clear in XHTML. The structure is more apparent, and the problem syntax is easier to spot; therefore, it is easy to author and maintain.

4. Ready for the future: The documents will be easily upgraded to the new version to take advantage of new features.

Disadvantages

There are no such direct disadvantages, but we will say there are a few limitations:

• It does not solve all cross-browser combability issues.
• It isn’t easy to begin as it is stricter, and sometimes you must think while developing new element names.

Required Skills

For learning, you should have some basic knowledge of HTML and XML. At least, it requires knowledge of their use and functionality. Any developer starting to learn XHTML might want to know the basics of web page development before proceeding, as it is the after version of HTML; it has the same structure as that of HTML.

Why Should We Use XHTML?

• It is compatible with all major browsers available in the market. We can write XHTML documents better to ensure smooth operation in existing browsers.
• It is more strict than HTML regarding syntax and case sensitivity, allowing developers to write code accurately.
• The documents are well-formed & consistent and can be parsed easily by current and future web browsers.

The design of the family accommodates the extensions provided by XML for developing new XHTML-based modules. These modules make combining new and old features easier while developing content.

範囲

特定の要件に応じて、HTML と XHTML のどちらかを選択したい場合は、両方のいずれかを検討するとよいでしょう。 HTML は Web ページ開発の基礎であるため、プロジェクト固有のニーズに応じて HTML も基礎となります。使用する人なら誰でも延長できます。現時点では HTML5 はすでに市場で入手可能であるため、特に開発をゼロから行う場合は、事前に検討する必要があります。

XHTML が必要な理由

HTML の改良版です。 HTML と XML の両方の力を組み合わせています。これらのテクノロジーを個別に使用すると、問題の解決策が得られます。

XHTML を学ぶのに適した対象者は誰ですか?

Web 開発を熱心に学ぶ人は誰でも XHTML を学ぶことができます。すでに HTML4 を使用している Web 開発者は、XHTML への切り替えを検討することをお勧めします。

このテクノロジーはキャリアの成長にどのように役立ちますか?

HTML 5 を含む多くの最新テクノロジーが利用可能であるため、特定の場合に役立ちます。学習は Web 開発者にとって確実に有益であり、キャリアの成長に役立ちます。
