The line-height property in CSS is used to control the height of a line of text within an element. It defines the amount of space above and below inline elements, such as text, to determine the overall height of a line.
Syntax
p {
line-height: 1.5;
}
The primary purposes of the line-height property include:
- Vertical Alignment: Ensures consistent vertical alignment of text within a line, evenly distributing space above and below the baseline.
- Improving Readability: Adjusts spacing between lines to enhance readability by preventing text from appearing too cramped or tightly spaced.
- Creating Vertical Rhythm: Establishes a consistent vertical rhythm across a webpage, contributing to a harmonious layout and a more visually pleasing design.
- Resolving Layout Issues: Helps address layout issues, especially when working with different font sizes and styles, ensuring proper alignment within a layout.
- Responsive Design: Supports responsive design strategies by allowing adjustments to line height for maintaining readability across various screen sizes.
- Unit of Measurement: Accepts various units, including unitless numbers, pixels, percentages, and em units, providing flexibility in defining the spacing between lines.
