Frequently Asked Questions

One of the key technologies for creating Web sites is HTML or hypertext markup language. Another is CSS, or cascading style sheets. In order to support a wide range of devices, HTML supplies the page’s structure while CSS handles its (visual and aural) layout.

Let’s see both of them separately:

HTML5 – It is the Hypertext Markup Language’s fifth version. This is the primary markup language for defining and organizing web page content. Every web page ever created has used HTML of some kind.

CSS3 – It’s the third, and the most recent edition is CSS3. The layout of websites, most of which were based on HTML, was revolutionized by CSS. A considerable deal of uniformity was achieved by specifying pages on a separate file known as a style sheet.

It’s best to use HTML and CSS for basic web creation. They may be considered the building blocks of web development, and the foundation must be very solid.

Some of the softwares which are best for HTML and CSS are:

  • Visual Studio Code
  • Sublime Text
  • Notepad ++
  • Atom
  • UltraEdit
