Study Notes

CSS: Cascading Style Sheets

Cascading Style Sheets (CSS) is a styling language used to specify the appearance of HTML elements. It allows web developers to create visually appealing and user-friendly websites by defining the layout, colors, fonts, and other visual properties of HTML elements. In this article, we will explore the basics of CSS, its syntax, and some practical examples to help you get started with styling your web content.

CSS Basics

To start using CSS, you need to link a CSS file to your HTML document using the <link> tag in the <head> section of your HTML file. For example:

<link href="styles/style.css" rel="stylesheet">

This line of code links to an external CSS file named style.css, which will apply the styles to the HTML elements in your document.

CSS Selectors

CSS selectors are used to target specific elements in your HTML document and apply styles to them. There are several types of selectors, including:

Type selectors: Target elements based on their HTML tag, such as h1 or p. For example:

h1 {
  color: red;
}

Class selectors: Target elements with a specific class attribute, such as .important. For example:

.important {
  font-weight: bold;
}

ID selectors: Target elements with a specific ID attribute, such as #example. For example:

#example {
  color: blue;
}

Attribute selectors: Target elements based on their attributes, such as [href]. For example:

a[href*="example.com"] {
  color: green;
}

CSS Properties and Values

CSS properties and values are used to define the appearance and layout of HTML elements. Some common properties include:

Color: Sets the color of an element's text and background. For example:

p {
  color: red;
}

Font: Specifies the font family, size, and weight of an element's text. For example:

body {
  font-family: Arial, sans-serif;
  font-size: 14px;
  font-weight: normal;
}

Background: Applies a background image, color, or gradient to an element. For example:

body {
  background-image: url("background.jpg");
  background-color: #f0f0f0;
}

Layout: Defines the position, size, and layout of elements on the page. For example:

container {
  display: flex;
  justify-content: space-between;
}

CSS Transitions and Animations

CSS transitions and animations allow you to create smooth visual effects when changing the appearance of elements on your page. For example, you can use the transition property to create a smooth animation when changing the color or size of an element:

p {
  transition: color 0.5s, transition-timing-function: ease;
}

In this example, the color of the paragraph element transitions from red to blue over 0.5 seconds using an ease transition.
