The gap between columns (in px, pt, em, etc.)
Syntax
column-gap: number | normal ;
number - The size of the gap between columns. It must not be negative, but can be equal to 0.
normal - Use the browser-defined default spacing, normally 1em.
The default value is auto.
Examples:
h1 { column-gap: 30px; }
.emw3class { column-gap: 8pt; }
#emw3id { column-gap: 0; }
Try it:
When text is displayed in newspaper columns the length of each line is much shorter. This is a great aid to readability. On the internet many people will skim read large blocks of text and this can have the unfortunate effect that they miss important points buried in a long paragraph. |
(CSS 3) Browser Support: IE 10, Opera. Use the equivalent -moz-column-gap for Firefox and -webkit-column-gap for Safari and Chrome.
