CSS Height/Width

In CSS, the height and width properties are used to define the dimensions of an element. Here’s how they work:

1. height property: It sets the height of an element, which determines the vertical size of the element. The value can be specified in various units such as pixels (px), percentage (%), viewport height (vh), etc.Example:css

.box {
  height: 200px;
}

width property: It sets the width of an element, determining its horizontal size. Like height, the value can be specified in different units like pixels (px), percentage (%), viewport width (vw), etc.

Example:

css

1. .box { width: 300px; }

It’s important to note that height and width define the content area dimensions of an element, excluding padding, borders, and margins. If you want to include those areas in the overall size of an element, you can use the box-sizing property with the value border-box.

Example:

css

.box {
  width: 200px;
  height: 150px;
  padding: 10px;
  border: 1px solid black;
  box-sizing: border-box;
}

In the example above, the total size of the .box element, including padding and border, will be 200px (width) by 150px (height).

Remember that the height and width properties can be used with various CSS selectors like class names, IDs, or element types to target specific elements on a webpage.
