HTML and CSS go hand in hand yet have differences. This article will deal with the difference between HTML and CSS deeps

What is HTML?

HTML is an abbreviation for Hypertext markup language. Before understanding what HTML is, let us help you by defining what hypertext and markup language is-

One of the fundamental aspects of the World Wide Web is hypertext, and web pages are frequently created using the Hypertext Markup Language (HTML). Hypertext is the text displayed on a mobile or computer screen or other electronic gadget and contains links (hyperlinks) to further material that the reader can access immediately. Links between hypertext documents are known as hyperlinks, and they are often activated by a mouse click, keypress combination, or touch of the screen. In addition to text, tables, graphics, and other presentational content types with incorporated hyperlinks are occasionally referred to as “hypertext.” Hypertext, as it is used on the Web, makes publishing material across the Internet simple.

A markup language is a collection of rules that stipulate what markup information can be used in a document and how we should mix it with the content to make it easier for people and computer systems to utilize. For creating web pages, HTML is a standard markup language. It also describes the structure of web pages and creates a link between them.

Key Features

Here are the critical features of hypertext markup language due to which it has gotten popular over the years:

Simple and easy-to-use: HTML can be written using annotations known as tags. The structure that tags provide for HTML helps both people and browsers understand the content effectively. This feature makes HTML user-friendly. Although HTML has hundreds of built-in tags, a developer only needs to be familiar with a small number of them for everyday use. All tags have worth, of course, even though many aren’t used in typical development.

SEO becomes your forte: The biggest USP (Unique Selling Point) of HTML5 is SEO (Search Engine Optimisation). With the development of search engines like Google, Yahoo!, DuckDuckGo, and others, you can access a wealth of knowledge. These search engines gather information from the World Wide Web by employing computer programs known as web crawlers.

A canvas for simple Game development: Simple games can be created with HTML5, but if you want to make a high-quality video game, you should use the canvas element, CSS, and JavaScript. You may satisfy both 2D and 3D games with Canvas. These games can be as interactive as you wish.

Wide platform independency: A browser, which can be found on practically any device with a primary Operating System, is what runs HTML. You would be aware that even older Nokia phones with Symbian OS could open HTML pages if you had used mobile phones before the advent of smartphones.

Its Semantic structure: HTML5 specifies distinctive tags to annotate various elements for their respective functions. For instance, the <article> tag is utilized to annotate page content. The content that is represented by the <aside> element is unrelated to the main subject of the page. <header>, <footer>, <div>, the paragraph tag <p>, and the tag that is most frequently used for page navigation, the <a> tag, are further significant components.

Supports various media: Due to its ability to display images, video, and audio, HTML has outstanding media-playing capabilities. The introduction of the video> and audio> tags in HTML5 has become much more straightforward. Of course, HTML5 allows you to do more than play video; you can specify controls, add images to buttons, and even programmatically control playback. A special mention should also be made of the <figure> tag, which has transformed how images are rendered on browsers. Along with the <figure> tag, we can use the <figcaption> to indicate captions.

What is CSS?

Cascading Style Sheets are referred to as CSS. CSS explains how HTML elements should appear on screens, printed materials, or other media. The color of the text, the font style, the spacing between paragraphs, the size and arrangement of columns, the background pictures or colors used, layout designs, differences in display for various devices and screen sizes, and a variety of other effects can all be controlled using CSS.

Key Features

Although CSS is simple to grasp and learn, it offers substantial control over how an HTML document is presented. CSS is mostly used in alliance with HTML or XHTML as markup languages. Here are its features-
