I wanted to know if there was a way to modify the back-end of Wordpress to do 2 things:

  • Make all tags' font the same size, so none are larger than the others
  • Always show the most used tags when creating/editing a post

This only applies to the back-end of Wordpress, not calling the tag cloud or any sort of front-end CSS that would be found in the theme.

use this at functions.php

    /* Tagcloud, change the font size */
function custom_tag_cloud_widget($args) {
    $args['largest'] = 13; //largest tag
    $args['smallest'] = 13; //smallest tag
    $args['unit'] = 'px'; //tag font unit
    return $args;
add_filter( 'widget_tag_cloud_args', 'custom_tag_cloud_widget' );

I think I have a simpler solution:

Install the plugin Add Admin CSS

Go to Settings and put this code:

p#tagcloud-post_tag.the-tagcloud a {
  font-size: 1em!important; 

I put 1em but feel free to put whatever value you prefer.


With wp_tag_cloud you can set the smallest and largest argument to the same value:

$args = array(
    'smallest'                  => 8, 
    'largest'                   => 8,
echo wp_tag_cloud($args);

Unfortunately, that would require hacking the Core. Also, unfortunately, I don't see a filter that will allow you to alter those argument directly, so you are going to have to do this a bit brute-force-y.

  function () {
      function ($return) {
        $pat = '|font-size: [0-9]+([^;]+)|';
        return preg_replace($pat,'8$1',$return);

Hooking to load-edit-tags.php should cause this to operate only on the wp-admin/edit-tags.php page on the backend, which is what I assume you want. Reference: http://codex.wordpress.org/Function_Reference/wp_tag_cloud
