Understanding the Basics of Cascading Style Sheets

What is CSS?

CSS, or Cascading Style Sheets, is a language used to style and layout web pages. While HTML structures the content of a webpage, CSS controls its appearance. This includes colors, fonts, spacing, and layout, providing flexibility and control over the visual presentation.

How CSS Works

CSS works by selecting HTML elements and applying styles to them. For example, you can change the color of text, the background color, or even add spacing between elements. CSS is often written in a separate file, linked to an HTML document, allowing the style of multiple pages to be managed from one file.

Why Use CSS?

Using CSS separates content from design, making websites easier to maintain. Rather than styling each HTML element individually, CSS allows for efficient styling across multiple pages, improving load times, consistency, and adaptability.

Basic CSS Syntax

The basic syntax of CSS includes selectors, properties, and values. Selectors target HTML elements, properties define what aspect to style (like color or font), and values assign specific styles to those properties.

• Selector: The HTML element you want to style, like h1 or p.
• Property: The aspect of the element to change, like color or font-size.
• Value: The style applied to the property, such as red for color.

Example of CSS Code

Here’s a simple example of CSS that changes the color and font size of a heading:

We can write above code into given syntax.

    h1 {
        color: blue;
        font-size: 24px;
    }
        

This code makes all h1 elements blue and 24 pixels in size.
