Die Erweiterung tut genau, wofür ich sie brauche und wofür sie beworben wird: Man kann mal eben schnell ein paar optische Anpassungen an einer Webseite machen, ohne direkt ein komplett anderes Theme oder einen "Styler" benutzen zu müssen. Die haben auch ihre Berechtigung, aber manchmal reicht es schon, wenn bspw. bestimmte Textblöcke einen ticken größer dargestellt werden.

I can't rate this extension yet but I'd like to. Looks like it requires jQuery? Getting this error in the Console: scripts.js:315 Uncaught ReferenceError: jQuery is not defined at scripts.js:315:4

Стиль CSS для документации Microsoft DotNET - удалось поменять. Стиль CSS для документации UNREAL ENGINE - трудно работает сам редактор (стили успешно меняются на сайте). Но проблема: обратный эффект - стили сайта влияют ПЛОХО - на стиль самого редактора строк этого Аддона). Становится сложно редактировать.

No longer works in 2023.

Отлично. Удалось, как и хотел, подвинуть панель управления видео на ютубе под плеер

I installed it for ad removing, but it brings much more ads than it removes.

Works for me. I use it to hide some live stats on Spotify. Which stresses me out :)

It has a global dependency on jquery, which has been falling out of fashion in recent years.

Works well for me

Best one so far. I wish we could make it retract the web page space instead of floating on top of it.

Перестало работать после обновления Хрома. Месяц назад было все ок, а сейчас при клике на иконку расширения ничего не происходит. При этом ранее созданные стили для сайтов продолжают работать.

The extension is very useful. However, it does not work on iframes.
JOEL
It was working.. then suddenly with Edge 100.x the tool's layout is messed up and can't interface with the editor. Too bad the developer on this project dropped support. :(
Joss
Clicking the button doesn't do anything
Brendon Williams
It doesn't actually show an editor anywhere? Clicking the button does nothing, and there's no editor in the options.
Mehdi Najaran
good
UFOnian (ゆーふぉにあん)
this doesn't overwrite a style that wrote on style attribute
yosef langer
good idea, but the extension gets affected by the pages RTL setting, and becomes unusable. you should set the whole extension window, or atleast code editor dir: ltr so it does not get affected by the pages settings.

Works great, but I wish it used something to sync data across devices, such as the Google Drive API.
Sam
A few issues, otherwise perfect: - you can't close the popup once it's open, you'll have to refresh the page. - the extension won't load in every domain. - the off button stops working once turned on.

Doesn't work at all in current Chrome build Version 96.0.4664.45 (Official Build) (x86_64) Haven't tried other versions

Super, bonne extension. Pour info la fenêtre ne s'ouvre pas sur "chrome://new-tab-page".
Alexander Designer
Excellent extension! It's really helpful to try out some new styles, hiding ads and adapt the styling of websites for your needs (e.g. increase font-size, adjust paddings, make better contrast, etc). Thanks a lot, Dimox! 🙌
Grigoriy Melnikov
Нажимаю на значек - ничего не происходит, в меню расширения так же нет ссылки для добавления css.
William Angel
Justo lo que necesitaba para personalizar ciertas página que visito regularmente y deseo quitar ciertos elementos o cambiar ciertos colores. El css que se escribe en la web queda guardado y se ejecuta cada vez que se carga la página. Excelente.
