CSS left Property

The left property in CSS is known to specify the horizontal position of the positioned element. This property has no effect on the non-positioned elements.

The effect of this property depends on how an element is positioned which means the value of the position property.

When both right and left values are defined, and the width constraints do not prevent it, the element gets stretched to satisfy both the values. In case the element is unable to satisfy both, then the position of the element is overspecified.

Syntax

left: length|percentage|auto|initial|inherit;

Example: CSS left Property

In the example below, we are using the left property to align our text according to the left property value specified by us. This means we are specifying the horizontal position of the positioned element.

We have given all the values and given different colors to our text in order to distinguish the text according to the different values.

Browser Compatibility

The term browser compatibility indicates the ability of a particular website to appear fully functional on several browsers, available in the market. This means that the HTML coding of the website and the scripts on that website must be compatible to run on the browsers. It is of immense importance today when there is a large variety of web browsers available.
