CSS Height and Width

In CSS, height and width are properties that are used to define the size of an HTML element.

Theheightproperty is used to specify the height of an element. It can be set to a specific value, such asheight: 100px, or a percentage value, such asheight: 50%. If the height property is not specified, the element will take up the height of its content.

Thewidthproperty is used to specify the width of an element. It can be set to a specific value, such aswidth: 500px, or a percentage value, such aswidth: 50%. If the width property is not specified, the element will take up the width of its content.

Here are some examples of using the height and width properties in CSS:

div {
  height: 200px;
  width: 300px;
}

img {
  height: 50%;
  width: auto;
}

In the first example, a div element is given a height of 200 pixels and a width of 300 pixels. In the second example, an img element is given a height of 50% of its parent element’s height (which will be determined by the height of the parent element), and a width that adjusts automatically to maintain the aspect ratio of the image.

It’s important to note that the height and width properties apply to the content area of an element, and do not include any padding, borders, or margins. If you want to include those in your calculations, you’ll need to add them separately to the total size of the element.
