What is Height in CSS?
In CSS, “height” refers to the vertical measurement of an element on a web page. It determines how tall an element should be, whether it’s a text box, an image, a container, or the entire page itself. Understanding how to set and control height allows you to achieve the desired layout and presentation of your content.
Setting the Height of an Element
You can specify the height of an element using CSS in several ways:
- Fixed Height: You can set a fixed height by specifying a value in pixels (px), ems (em), or other units. For example:
.container {
height: 200px;
}This sets the height of the element with the class “container” to 200 pixels.
- Percentage Height: You can set the height as a percentage of the containing element’s height. For instance:
.box {
height: 50%;
}This will make the height of the element with the class “box” half the height of its parent container.
- Auto Height: Elements can also have an “auto” height, which adjusts to the content inside the element. For example, an element containing text will automatically adjust its height to fit the text.
- Viewport Height (vh): You can use viewport units to set the height based on the height of the viewport (the browser window). For example:
.full-height {
height: 100vh;
}This sets the height of the element to be equal to the height of the viewport.
Example: Creating a Simple Card Layout
Let’s create a simple card layout using height in CSS. The following HTML and CSS code will help us achieve this:
HTML:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
<div class="card">
<h2>Card Title</h2>
<p>This is a sample card.</p>
</div>
</body>
</html>CSS (styles.css):
.card {
width: 300px;
height: 200px;
background-color: #f0f0f0;
border: 1px solid #ddd;
border-radius: 5px;
text-align: center;
padding: 20px;
margin: 20px;
}In this example, we’ve created a simple card with a fixed height of 200 pixels. You can adjust the height and other properties to achieve your desired layout.
