    To build a website, we require some tools to give a proper structure to web pages and style them. A website is a collection of multiple web pages, and to design those pages we use languages like HTML, CSS, and JavaScript. These three languages are essential for client-side or front-end development. Also, among these languages, HTML is a markup language, CSS is a styling language, and JavaScript is a scripting and programming language .

    For individuals who are new to web development, HTML vs CSS is a debate that they likely come across. This article contains all the essential information that you need to understand the difference between HTML and CSS. So, let's get started!

    HTML vs CSS: Overview

    Both HTML and CSS are essential for building modern websites and web applications. While HTML defines the general structure of a web page, CSS helps to style the elements on a web page and also defines the layout. HTML uses tags and attributes to specify the proper structure, whereas CSS uses those tags and attributes to style the webpage content.

    Also, CSS is responsible for controlling the webpage presentation, which includes page color, fonts, and layout. The upcoming sections have covered all the significant differences between HTML and CSS that you must know if you want to work as a web developer.

    What is HTML?

    Tim Berners-Lee introduced HTML in 1989 as a standard language for the web. The main objective of HTML is to provide the necessary structure to the web page so the content of the page can be described easily. HTML uses tags to describe the overall structure of the webpage as well as the structure of the content.

    Every HTML document contains a” HTML document type declaration” <!Doctype HTML>, which describes the basic version of HTML. The latest version of HTML is HTML5. The document type declaration helps the browser to identify the version of the document, and the browser parses that HTML document accordingly.

    What is CSS?

    In 1996, CSS was developed by Håkon Wium Lie, Bert Bos, and World Wide Web Consortium (W3C). CSS was designed to manipulate the styling of HTML elements , which includes font size, text color,  layout, etc. Right now W3C maintains CSS. CSS use a pair of property and value {property:value} to change the default HTML style. Also, CSS uses the selector to target the HTML tag that needs to be styled and uses the property-value pair to change the style.
