CSS Selectors and Properties: The Basics You Need to Know

Introduction

CSS (Cascading Style Sheets) is the backbone of web design, allowing developers to control the look and feel of websites. To effectively style web pages, you need to understand CSS selectors and properties. In this guide, we’ll break down the basics and how they help define the appearance of HTML elements.

What Are CSS Selectors?

CSS selectors are patterns used to target specific HTML elements for styling. They tell the browser which elements to apply styles to. There are different types of selectors:

1. Universal Selector (*)

Applies styles to all elements on a page.

* {
    margin: 0;
    padding: 0;
}

2. Element Selector

Targets specific HTML elements like <p>, <h1>, and <div>.

p {
    color: blue;
}

3. Class Selector (.)

Selects elements with a specific class attribute.

.red-text {
    color: red;
}
<p class="red-text">This text will be red.</p>

4. ID Selector (#)

Targets an element with a unique ID.

#header {
    background-color: black;
    color: white;
}
<div id="header">Welcome</div>

5. Grouping Selector (A, B)

Applies styles to multiple elements at once.

h1, h2, h3 {
    font-family: Arial, sans-serif;
}

6. Descendant Selector (A B)

Targets elements inside a specific container.

div p {
    font-size: 18px;
}
<div>
    <p>This paragraph inside a div will be affected.</p>
</div>

What Are CSS Properties?

CSS properties define how elements look and behave. They are paired with values to control appearance.
