This extension is very useful. It highlights the matched css elements with count. The css patch code you wrote only activated when edit window is activated - which is nice. Reload page won't lost your code is good.
LIXO.
It great !!!!!
руками все туда писать надо (( ни какой вспомогалки. Имена шрифтов руками. Толку от этого.
nice
Great extension. Very helpful to us a developer.. GOOD JOB!
This extension is great! It allows me to pinpoint specific css modifiers to overwrite them properly. I'm not sure why anyone else has problems with this extension, but it works great for me!
Won't work
Muy útil. Escribe tu código CSS en una pequeña ventana junto al navegador y visualiza instantáneamente los cambios que se producen.
Worthless to me. If you add a background color to a div, the editor changes as well. I suppose it works fine for everything that has a specific class or id, but for spans, divs, etc, it only causes issues.
