সাঁচ:Font-size/doc

This template uses a <span> element for formatting.
Block-based templates and paragraph breaks cannot be nested inside it.

See H:DIVSPAN for details.

Purpose

This template simplifies formatting text that has a specified font-size in line.

{{font-size|150%|font-size}}

displays:

font-size

{{font-size|150%|style=color:#FF0000|RED}}

displays:

RED

While `{{font-size\|200%\|Lorem<br />ipsum}}` displays	Lorem ipsum
`{{font-size\|200%\|line-height=100%\|Lorem<br />ipsum}}` gives	Lorem ipsum

sizes expressed as a percentage or in 'em' will give the best results
using a size of 100% allows the template to change only the color
if the text being resized contains an equal sign it needs to be written as {{=}}

Please note that none of these fonts have proportional line height to the font size. Line height is only relevant with fonts smaller than 100%. For these, see:Fonts smaller than 100% with proportional line heights
