Meet CSS Hero
CSS Hero is the definitive WordPress plugin to easily customize the look of your Themes and Plugins with an easy and intuitive point and click interface. It will allow you to easily change colors, fonts, backgrounds, pretty much whatever on your site.
Purpose of the plugin
It’s like a precise painting brush to refine the looks of your site.
It is NOT a bulldozer to revolutionize your Theme’s structure, or edit content in any way.
How does it work, technically?
In a nutshell, it’s nice, clean, and non-destructive: CSS Hero is a live WordPress Theme editor that works without modifying any of your theme files.
It’s easy to grasp visual CSS editing interface will allow you to visually tweak your site, without harming performance & speed: CSS Hero is widely compatible with many environments and it is built to be light and tolerant.
You can use CSS Hero to visually customize the vast majority of WordPress Themes and Plugins out of the box: CSS Hero does it’s best to pick up the right CSS selectors automatically.
From a technical standpoint, CSS Hero only generates and enables an extra CSS stylesheet that cleanly overrides your Theme’s original stylesheet.
This CSS stylesheet is a single static file, so your site will not be any slower when browsing it.
No other resources are consumed, no other script is added, no php, no js, no bloat whatsoever is added to your site.
For your convenience, your edits are also stored as data in the database as well, in a specific, separate database table, typically wp_csshero5.
These data are accessed only while editing with CSS Hero and hold up your editing history as well.
Performance-wise, since all the heavy lifting is just done by your own browser, and only while using the editor, the server side impact it’s almost zero.
