Understanding CSS padding-left for Better Web Design

The padding-left CSS Property

The padding-left CSS property sets the space on the left side of an element, between its content and its border. This helps web developers control the layout and readability of web pages.

Values

You can set padding-left using these values:

• Length: A fixed value like 0.5em, 0, or 2cm.
• Percentage: A percentage of the containing block’s width, like 10%.
• Global values:
  • inherit: Uses the padding-left value from the parent element.
  • initial: Sets the padding-left value to its default.
  • revert: Resets the padding-left value to the browser’s default.
  • revert-layer: Resets the padding-left value to the previous cascade layer’s value.
  • unset: Resets the padding-left value to its inherited value if it inherits, or to its initial value if it does not.

Negative values are not allowed for padding.

Syntax

The padding-left property follows this syntax:

padding-left = <length-percentage [0,∞]>

<length-percentage> =
  <length> | <percentage>

• Length: A fixed length value, like px, em, cm, etc.
• Percentage: A percentage value relative to the width of the containing block.

Examples

To add a 15px padding on the left side of an element, use:

padding-left: 15px;

You can also use the shorthand padding property:

padding: 10px 15px 20px 25px;

Here, 25px represents padding-left.
