  • (2019-07-24) Władzix 2: Incredible! Everything I was searching for, runs Live so you dont have to run every time you edit something,very nice suggestions while typing and other small features like colors are displayed in squares while typing names. The one of the best features is auto enable on websites. I have made dark theme mode for some websites, thanks to this extension! Awesome!!!

  • (2019-06-01) Sharko Ots: On ne ne peut pas éditer les fichiers html locaux, mais appart ça l'extension est extrêmement utile et très bien réalisée. Je l'utilise depuis au moins un an je crois, et je n'ai jamais eu aucun problème. Elle sauvegarde très bien le css quand on quitte la page et l'interface est très intuitive.
  • (2019-06-01) Farzin Hatami: Sometimes is useful, but not always...

  • (2019-05-05) Sabin Petre: Este perfect,ceea ce imi trebuia demult.Imi place ca se mareste,micsoreaza si se poate muta acolo unde doresc.
  • (2019-04-22) Siniša Petrović: Nice extension but, you can't use it in mobile view, because it's loaded inside the window. That's a big issue.
  • (2019-04-12) Nancy M Schorr: Awesome! Fixed the Google Tasks problem with the canvas view being obsolete. Thank you! Here's what I did: 1) install this extension: 'Live editor for CSS, Less & Sass - Magic CSS' 2) put this css into the extension's css editor: .gb_gd,.gb_Md,.gb_od,.gb_Zb { display: none; } .brC-brG { width: 100vw!important; } .G4zhSc,.CTxcDf { width: 100%; } Set it to apply automatically (little icon at top of extension's window). To get it to work I need to click on the Extension icon in the address bar to activate it (not sure why), then press F12 to bring up devtools (not sure why either). That's it!
  • (2019-04-11) Krystian Jakubowski: Best plugin for editing CSS styles, also handful LESS and SASS editor. Thank you for great plugin :)

  • (2020-01-13, v:7.0.7) Ben Cheshire: Custom CSS for iframes overwrites the parent page's CSS too
    When working in an iframe, if the parent page is refreshed, the custom CSS for the parent page will sometimes (but not always) be overwritten by the iframe's CSS. It's just a minor annoyance for me as I don't need the parent page to have custom CSS, so I just remove the entire block every time it happens. There was one occasion where the parent frame's CSS overwrote the iframe's CSS, luckily I already had a backup of the stylesheet.

  • (2019-08-19, v:7.0.7) Simon Edwards: URL changed, cannot access my code to copy/restore it to the new URL
    Hello, Love the extension, I've been using it for a very long time. I'm running into an issue where the URL of a website I've heavily customized has changed its URL e.g. example1.domain.com to example2.domain.com which means all of my CSS got reset. Is there any way for me to access my old CSS which is still stored on example1? I cannot get to the old URL as it immediately redirects to the new URL so I'm a bit stuck, and I've got about 8 months worth of CSS stored in there. Kind regards, Simon
  • (2018-12-24, v:7.0.7) Moataz AbdAlmageed: Thanks for the awesome extension
