Height and Width in CSS
Height and Width are properties in CSS which are used to set the height and width of boxes or elements.
The height and width properties don't include margins, borders, or paddings. It only sets the height/width of the region within the margin, border and padding of the element.
Values of Height and Width in CSS
It’s value can be adjusted using length, percentage, auto, etc.
- auto - This is default value. The browser automatically calculates the height and width
- length - Defines the height/width in cm, px etc.
- % - Defines the height/width in percentage of the containing div/block
- initial - Sets the height/width to its default/original value
- inherit - The height/width will be inherited from its parent value
Example:
<!DOCTYPE html>
<html>
<head>
<style>
div {
width: 50%;
border: 5px solid black;
font-size:42px;
font-weight:bold;
color:maroon;
padding: 50px;
margin-left:50px;
}
</style>
</head>
<body>
<div>OpenGenus.</div>
</body>
</html>
Output:
Note: Remember that the height and width properties do not include margins, borders, or paddings. It only sets the height/width of the area or region inside the margin, border, and padding of the element.
Setting Height and Width of a Image
The value of image can be similarily adjusted using px, cm, percentage, etc.
Example:
<!DOCTYPE html>
<html>
<head>
<title>Height and width of image</title>
<style>
.open-genus {
width:300px;
height:200px;
border:3px solid black;
}
</style>
</head>
<body>
<img class="open-genus" src="https://avatars.githubusercontent.com/u/18506046?s=280&v=4">
</body>
</html>
Output:
Setting max-width and min-width of an Element
- max-width: The max-width property is used to set the maximum width of an element or box. It’s effect can be seen by resizing the browser's window.
Example:
<!DOCTYPE html>
<html>
<head>
<title>max-width of element</title>
<style>
.open-genus {
max-width:500px;
border:2px solid black;
}
</style>
</head>
<body>
<div class="open-genus">

Output:
Note: If you for some reason use both the width property and the max-width property on the same element, and the value of the width property is larger than the max-width property; the max-width property will be used (and the width property will be ignored).
The problem here with the <div> occurs when the browser window is smaller than the width of the element and the browser then adds a horizontal scrollbar to the page.
Also, using max-width instead, in this situation, will improve the browser's handling of small windows.
- min-width: It is used to set the minimum width of an element or box. It’s effect can be seen by resizing the browser's window.
Example:
<!DOCTYPE html>
<html>
<head>
<title>min-width of element</title>
<style>
.open-genus {
min-width:400px;
border:2px solid black;
}
</style>
</head>
<body>
<div class="open-genus">
