max-width

Defines the maximum width a region may expand to if it is relatively sized. Useful to constrain large regions of text from having overly long lines, which can result in readability problems. Measurements are generally in fixed values although relative units such as percentages may be used.

Example

#div1 {width: 50%; max-width: 800px;}
