Hypertext markup language, HTML, is what the web is ultimately made up of. HTML is one of the basic languages taught to children with computer subject. This language is written in tags. The input of the content is made through the tags <>, and the output is observed in web browsers.

All web browsers support HTML. Many other web development languages have been derived from HTML. All types of content including but not limited to pictures, text, tables or other data can be inserted in between the tags with appropriate syntax.

HTML even allows users to embed other scripts in the webpage and modify the behavior of the content. It is quite simple and easy to understand, and the BASIC unit of all web coding is still very popular.

CSS, Cascading Style Sheets, help you determine how well the content has been inserted and accordingly, you can make changes to the HTML coding. This is done by adjusting the indentation, alignment, paragraphs, fonts, colors, and multitudes of options for the formatting of the content. CSS allows you build up the markup language with HTML or XML to enhance the aesthetic value and presentation of the web page.
