- SVG: Scalable Vector Graphics, a format for rendering two-dimensional images.
- CDN: Content Delivery Network, a system of distributed servers that deliver web content.
Getting Started with Bootstrap Icons
Let’s start with the simplest example of using Bootstrap Icons. First, we’ll set up our HTML file and include Bootstrap Icons via a CDN. This way, you don’t have to download anything, and you can get started right away!
<!DOCTYPE html>
<html lang='en'>
<head>
<meta charset='UTF-8'>
<meta name='viewport' content='width=device-width, initial-scale=1.0'>
<title>Bootstrap Icons Example</title>
<!-- Include Bootstrap Icons CSS -->
<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/bootstrap-icons/font/bootstrap-icons.css'>
</head>
<body>
<h1>Hello, Bootstrap Icons!</h1>
<p>Here's a simple icon: <i class='bi bi-alarm'></i></p>
</body>
</html>This code sets up a basic HTML page and includes the Bootstrap Icons CSS from a CDN. The <i class='bi bi-alarm'></i> line adds an alarm icon to the page. You should see a small alarm icon next to the text when you open this HTML file in a browser.
Expected Output: A webpage with the text “Hello, Bootstrap Icons!” and an alarm icon next to “Here’s a simple icon:”.
Progressively Complex Examples
Example 1: Adding Multiple Icons
<!DOCTYPE html>
<html lang='en'>
<head>
<meta charset='UTF-8'>
<meta name='viewport' content='width=device-width, initial-scale=1.0'>
<title>Multiple Bootstrap Icons</title>
<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/bootstrap-icons/font/bootstrap-icons.css'>
</head>
<body>
<h1>Multiple Icons</h1>
<p>Alarm: <i class='bi bi-alarm'></i></p>
<p>Battery: <i class='bi bi-battery'></i></p>
<p>Camera: <i class='bi bi-camera'></i></p>
</body>
</html>In this example, we’ve added three different icons: an alarm, a battery, and a camera. Each icon is represented by an <i> tag with a specific class name. You can find a list of all available icons and their class names in the Bootstrap Icons documentation.
Expected Output: A webpage displaying an alarm, battery, and camera icon next to their respective labels.
Example 2: Customizing Icon Size and Color
<!DOCTYPE html>
<html lang='en'>
<head>
<meta charset='UTF-8'>
<meta name='viewport' content='width=device-width, initial-scale=1.0'>
<title>Custom Icon Styles</title>
<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/bootstrap-icons/font/bootstrap-icons.css'>
<style>
.icon-large {
font-size: 2em;
color: red;
}
</style>
</head>
<body>
<h1>Custom Icon Styles</h1>
<p>Large Red Alarm: <i class='bi bi-alarm icon-large'></i></p>
</body>
</html>Here, we’ve added some custom CSS to change the size and color of the alarm icon. By adding the icon-large class, the icon becomes larger and turns red. This demonstrates how you can easily customize icons to fit your design needs.
Expected Output: A webpage with a large red alarm icon next to the text “Large Red Alarm:”.
Example 3: Using Icons in Buttons
<!DOCTYPE html>
<html lang='en'>
<head>
<meta charset='UTF-8'>
<meta name='viewport' content='width=device-width, initial-scale=1.0'>
<title>Icons in Buttons</title>
<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/bootstrap-icons/font/bootstrap-icons.css'>
<style>
.btn {
display: inline-flex;
align-items: center;
padding: 0.5em 1em;
background-color: #007bff;
color: white;
border: none;
border-radius: 0.25em;
cursor: pointer;
}
.btn i {
margin-right: 0.5em;
}
</style>
</head>
<body>
<h1>Icons in Buttons</h1>
<button class='btn'>
<i class='bi bi-download'></i> Download
</button>
</body>
</html>This example shows how to use Bootstrap Icons within a button. The icon is placed inside the button element, and some basic styling is applied to make it look like a typical button. The icon enhances the button’s appearance and provides a visual cue for the action it performs.
Expected Output: A webpage with a button labeled “Download” with a download icon to the left of the text.
