  • (2021-04-20) Андрей Коперский: Возникнла задача скрыть нотификацию другой команды для демо. Плагин решил "на ура"! Отлично!
  • (2020-09-06) Pixelsplasher: It doesn't always save my CSS edits. I have to keep refreshing the page to see if it saved and view my changes. I wish there was a better extension than this but it seems to be the best one available so I will have to put up with it.
  • (2020-08-07) Tymski: It's not injected at the end of the css cascade rules, so your rules are overwritten by the page rules. You have to !important everything, but it doesn't always work because frameworks utilize !important themselves. Doesn't live reload the css. Sometimes it doesn't update at all even if I Hard Refresh and clear cache on the right click refresh button, then I need to refresh the extension from the extension page. Apply to domain checkbox unchecks itself for no reason at all. Doesn't auto-complete classes from the page. No parenthesis matching, no linting, no prettifying, no nothing.
  • (2019-12-10) Arnaud Sanchez: Seems useless to me : need to reload the page for styles to be applied.
  • (2019-09-16) Gilles Cavin: Works!
  • (2019-08-14) yusuf Sunset: Is working properly
  • (2019-05-10) Eric Hertenstein: So simple! Quick and easy way to add a few persistent style changes to any site you visit. Also, unlike some similar extensions I've tried, this one doesn't modify code in iFrame WYSIWYG editors, it just straight-up adds a style block to the bottom of the document body, and that's it.
  • (2017-11-13) Davide Ξ: L'unico che injetta il codice js direttamente dentro l'html, come se fosse parte integrata (altri tool non accedono a variabili della pagina). Migliorabile l'interfaccia grafica, ma fa il suo dovere.
  • (2017-02-28) M G: Simple and works!
  • (2016-12-19) Артур Шарафутдинов: Инжекты работают, но только для конкретного адреса страницы. Не работает на домен, а работает на страницу - не очень удобно. Works good, but only per page, doesn't work for domain.
  • (2016-06-01) Jockson: Инжектит в страницы localhost стиль, коверкающий содержимое.
  • (2016-02-16) Sasha Rio: Супер!
  • (2015-02-21) Matt Haidet: I really liked this. I only wish you could add some real-time functionality so that as I'm typing it would change and so that I don't have to refresh the page.
  • (2015-01-21) Aamir Shahzad: good..
  • (2015-01-21) Zohaib Hassan: Very helpful.

  • (2023-02-28, v:1.90) Jovan Ralic: Seems great. Would like a few additional features...
    I spent hours, looking for a CSS editor that sinks the data to the account, so that it's available on my other machine. Thank you!! Please, consider adding these features: - Apply CSS immediately - Place CSS and JS in separate tabs, instead one above the other - Option to move the window around and resize it, like this extension does: https://chrome.google.com/webstore/detail/live-editor-for-css-less/ifhikkcafabcgolfjegfcgloomalapol - Dark mode
  • (2023-01-04, v:1.90) Yannick Lämmel: Wildcard
    Hi ;-) Is there a possibility to make a css or js like wildcard? That it works für all sub)pages of a website? Like website.com/*
  • (2022-03-13, v:1.90) codernize: Some improvements and suggestion
    Hi, nice work. Would love to use your extension but my workflow would benefit better from a different approach. What if you were to make it automatically inject some js and css to any page, and those resources and retrieved from a link, like for example a github repository. It would be possible to make custom navigation methods, or making own dark mode for every site just from one repository. Pull that baby down, make some changes, push them and see it on your next page reload. And it would be best if the code can be open source... I mean, it's a must. Let me know if you're thinking of going on this road, or I'll have to search for another way, or simply making an extension on my own. Happy coding ;)
  • (2021-12-16, v:1.89) Jon Seidel: How to remove injected code?
    I've tested the code; now I want to remove it -- how do I do that?
  • (2021-04-30, v:1.87) songloi mr: open source
    this extensions have open source on github?
  • (2021-04-23, v:1.87) Robert V: windows 10 chrome issues
    I injected a javascript several times and it messed something up with the script, i unisntallted chrome completly and deleted the extensions, just wondering what files could have been changed where a system restore might be necessary to fix? Thanks
  • (2019-08-07, v:1.7) Rene Hefner: won't inject if loaded in iframe
    Hi if I load a page directly it works fine, I am using the tool to build an embedded mockup of a website but if I load the page via an iframe it does not inject even if on domain level is selected.
  • (2019-01-11, v:1.7) Patrick Danielsson: Support for @media
    It seems like I can't add @media in the CSS injector, else I'm doing something wrong. Example: @media only screen and (max-width: 750px) .content-container { margin-top: 0px; } }
  • (2018-08-06, v:1.7) Abuzer Firdousi: Please suggests what can be added to this extension?
