Introduction
Cascading Style Sheets (CSS) is a stylesheet language used to describe the presentation of a document written in HTML or XML. It can control the layout, font, color, and other visual aspects of a webpage. CSS is essential for web development, and it is used in conjunction with HTML and JavaScript to create beautiful, responsive websites. In this beginner's guide to CSS, we will cover the basics of CSS, including how to use CSS selectors, properties, and values.
CSS Syntax
CSS has a simple syntax that consists of a selector, a property, and a value. The selector targets the HTML element you want to style, the property sets the style you want to apply, and the value specifies the value of the property. Here is an example of the basic CSS syntax:
selector {
property: value;
}
Selectors
Selectors are used to target specific HTML elements to apply CSS styles. There are different types of selectors in CSS, including element selectors, class selectors, and ID selectors.
Element selectors target all instances of a specific HTML element. For example, the following CSS rule targets all paragraph elements on a webpage:
p {
color: red;
}
Class selectors target HTML elements with a specific class attribute. For example, the following CSS rule targets all elements with the class "example":
.example {
color: blue;
}
ID selectors target a single HTML element with a specific ID attribute. For example, the following CSS rule targets the element with the ID "header":
#header {
background-color: yellow;
}
Properties and Values
CSS properties specify the visual style you want to apply to an HTML element. There are hundreds of CSS properties to choose from, including font, color, background, margin, padding, and more. Each CSS property has a corresponding value that specifies the specific style you want to apply.
Here is an example of a CSS rule that sets the font size and color for all paragraph elements:
