HTML (Hypertext Markup Language) is the standard markup language used to create web pages. It allows developers to structure, format, and style text content on a webpage, creating interactive elements like forms, images, videos, and more.

HTML includes tags with predefined properties that enable you to control how the content appears in a browser.

HTML documents are composed of two parts: the head and the body. The head contains information about the HTML document such as its title and any other metadata, while the body holds all of the visible content that appears on a webpage.

When coding an HTML document, you’ll need to open up a text editor like Notepad or Atom, type in the following code, and save the document as a .html file:

<!DOCTYPE html>





<body>   </body>

The basic tags in HTML enable you to structure and customize the content of your webpage. Here’s a quick overview of some commonly used HTML tags that help developers add images, lists, text formatting, tables, and more:

  • <p>: Creates a paragraph
  • <h1>-<h6>: Creates heading sizes ranging from 1 to 6
  • <img>: Adds an image onto the page
  • <a>: Add hyperlinks that link to other websites
  • <ul>, <ol>: Creates unordered and ordered lists respectively
  • <div>: Enables text formatting through the use of classes, ids, and other attributes

Below is some important information about CSS.

·       What is CSS and what can it be used for Web Development?

CSS (Cascading Style Sheets) is a styling language used to describe how the HTML elements on a web page should look.

It provides developers with the ability to control the layout, color, font size, and other visual aspects of the webpage content. CSS is also used to create mobile-responsive websites that adjust according to the device being used by the visitor.

  • How to create a CSS file?

You can create a CSS file simply by opening up a text editor and typing in the styling code. Then, save the document as a . CSS file. Here’s an example of some basic CSS code that sets the font size, color, and background color of a webpage:

body {

font-size: 12px;

color: blue;

background-color: white;


·       What are the different types of CSS styles in Web Development?

There are three different types of CSS styles that can be used to style a webpage. These include internal, external, and inline styles. Internal styles involve adding the CSS code directly into the HTML document using a <style> tag.

External styles involve creating an external CSS file and then linking it to the HTML document. Inline styles are added directly into individual HTML elements in order to override any other existing styling rules.
