===== Description =====

This plugin allows to write text in different sizes.

===== Syntax =====

Enclose the text in ''%%##%%'' tags to make it larger, and in ''%%,,%%'' to make it smaller.

Add more ''#'' or '','' to increase or decrease the size in steps of 20%.

  ##this text is shown at 120% of the base size##, ###this is 140%### ####and this is 160%####
  ,,this is smaller, at 80%,, and ,,,this is at 60%,,,
  ,,if I were to put a comma after a small text,,%%,%% I would need to enclose the comma in double percent signs

===== Source Code =====

Create a directory ''fontsize'' in ''/wiki/lib/plugins'' and save the code in a ''syntax.php'' file there.

<code php syntax.php>

===== Discussion =====

Hi. Is is me or I can't get the system to recognize a link if it's put in smalltext?

<code>
,, [[http://www.giocoestudio.it|programma]] ,,
</code>

this does not work...

Tnx!

-------
Work neither with H1, H2, H3 etc titles :(

<code>

</code>

Too bad.

Hi!

You can solve this problem by patching the plugin with the function below:

<code php>
    function getAllowedTypes() {
        return array('formatting', 'substition');
    }
</code>

See also [[devel:syntax_plugins#synopsis]] for ''getAllowedTypes()''.

------- 

Hi! I have fontsize2 up and working, but fontsize does not. 
Have the syntax.php in the plugins folder, but the plugin does not work and does not appear 
in plugins in the config. 
Why :-? 

-------

I can not seem to get this to work for a page of text. All the line breaks stop working. Maybe because I'm using the xbr plugin?

-------
Patching plugin works, thank you!

--------

I wanted to link to a larger text, like

<code>
[[fs|####test####]]
</code>

but the number-signs are not resolved. I tried adding the patch above in syntax.php, but it did not work. Outside of the links, it works fine. Any idea?
