## Description

Extension allows you to identify elements that have a negative impact on the performance of the CSS code. There are two modes of operation and two display modes.

-Operation modes-
Loaded: The extension identifies elements that take a long time to render, thereby slowing down the page loading.
Unused: The extension identifies elements with unused styles.

In both modes, the elements are sorted in descending order.

-Display modes-
Constant: Highlighted elements are displayed continuously, allowing you to analyze them.
Fading: Highlighted elements lose their transparency, the mode is suitable for general analysis of the picture.

-Important-
You cannot use a class with the name - cssCleaner.
You cannot use an id with the name - cssCleanerStyle.
It is not advisable to use the search button a large number of times.

-Additional-
All modes return the viewed page to its original form. Two languages ​​are available: Russian and English. The mode for detecting unused styles in components works according to the table, so the extension does not notice all styles yet.
