CSS Width is a property that allows the developer to specify the width of an element.
The syntax for defining the width of an element is as follows:
selector {
width: value;
}
Where selector
is the element to which the width is being applied, and value
is the width to be set. The value can be a number followed by a unit of measure (such as px
, em
, or %
), or it can be one of the following keywords:
auto
: The default value. The element's width is determined by its content.inherit
: The element inherits the width of its parent element.initial
: The element is set to its default width.To set the width of an element in pixels, use the following syntax:
div {
width: 200px;
}
To set the width of an element as a percentage of its parent element's width, use the following syntax:
div {
width: 50%;
}
To set the width of an element to be determined by its content, use the following syntax:
div {
width: auto;
}
To make an element inherit the width of its parent element, use the following syntax:
div {
width: inherit;
}
In conclusion, CSS Width is a very useful property for controlling the size of elements on a web page. It allows developers to set the width of an element using pixels, percentages, and other units of measure.
