Hypertext Markup Language (HTML) and Cascading Style Sheets (CSS) are two other programming languages that developers use in frontend development. HTML is the basic building block of most webpages. All the paragraphs, sections, images, headings, and text are written in HTML. The content appears on the website in the order it is written in HTML.
CSS is a language of style rules that we use to apply styling to our HTML content. You can use it to design website elements such as background colors, fonts, columns, and borders.
HTML vs. CSS vs. JavaScript
All three languages work together to create a positive user experience on any site. While HTML and CSS can mainly manipulate static content, they can integrate with client-side JavaScript code to dynamically update content too.
For example, the script code block on an HTML page can contain JavaScript within it. The browser can then process both HTML and the internal JavaScript code when the HTML page loads in the browser.
