Really good, after the new update of Styler i'm glad i found this extension. It's to bad that you have to code in a new tab but all the options are worth it !
such a beautiful extension for applying wide variety of css across websites ( with wildcard * filters)..editor has auto completion , suggestions and validation features and to detect what is wrong in css.
First of about 10 injectors that can actually inject a localhost-ed script and do it automatically. So i can code extension in my favorite browser and reload the site any time i make changes. Thx.
This is exactly what I'm looking for
I use it all the time, and it works wonderfully. Great extension.
Работает как положено, вот только на примере ВК(думаю связано с JS роутингом) если на определенной странице редактировать CSS(на примере JS не знаю), то без полного обновления страницы не обойтись. Как у меня: на своей странице я скрыл несколько блоков(типа информации о себе) и если я например после новостей перейду на свою страницу то блоки на месте пока я не обновлю страницу.
it's so greatand convenient！i suggest you should try it.
Шикарно очень удобно теперь пользуюсь только им
Супер! Давно искал такое расширение. Молодцы разработчики! Это автоматизирует мой процесс очень здорово! Ставлю Отлично!
It's perfect, but still one thing is bothering me. CSS: div[style="text-align:center;margin:0 auto;width:300px;height:250px;"] { display: none; } I use this rule with "stylebot" (chrome extension), it works, but not with this extension (User JavaScript and CSS).
