line-height | NN 4 IE 4 CSS 1
| Inherited: Yes
Sets the height of the inline box (the box holding one physical line of content). Under normal circumstances, the line-height of the tallest font in a line of text or the tallest object governs the line height for that content line. Mainstream browsers have come a long way since the Version 4 wrinkles that frequently made a visual mess out of mixed font sizes and line heights in the same block-level element.
CSS Syntax
    line-height: normal | number | length | percentage
Value
A value of normal lets the browser calculate line spacing for the entire element, thus producing a computed value that can be inherited by nested elements. A number value (greater than zero) acts as a multiplier for the font-size of the current element. Therefore, if a nested element inherits the line-height multiplier from its parent, that multiplier is applied to the current element's font-size setting (the multiplier, not the computed value of the parent, is inherited). A length value assigns an actual value to the inline box height. And a percentage value is a multiplier applied to the font size of the current element. In this case, the computer value can be inherited by nested elements.
Initial Value
normal
Example
    p {line-height: normal}    /* Browser default; actual value is  inheritable */
    p {line-height: 1.1}       /* Number value; the number value is inheritable */
    p {line-height: 1.1em}     /* Length value; the actual value is inheritable */
    p {line-height: 110%}      /* Percentage value; percentage times font size */
                               /* is inheritable /*
Applies To
