Image from store CSS and Javascript Injection

Description from store You can inject css/javascript code to web pages with this plugin. And it will remember the code you injected for different websites. Finally, these code will be auto-injected next time you open the website. The code pieces are grouped by host. The source code is hosted in github: https://github.com/comcaptain/chrome_plugins. You can submit bugs there. 1.0.5 update: 1. fix ace editor redraw bug 2. now js will only be executed when page is loaded 3. add external css resource tab: urls are seperated by line you can use alias for url, now there's only one alias(bootstrap -> https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css). Contact me if you have other need for alias([email protected]) 4. now js will be executed before the page is fully rendered to avoid FOUC 5. now you can inject jquery code in pages without jquery(jquery-2.1.4) version 1.0.6 update log: 1. guarantee injected css/js appear after original page's css/js references in head tag 2. fix updateCss execution timeline 3. fix bug: do not update css after css text is cleared

(2020-07-21) Harly Walsh: Beautiful; does what it's told. Best one I've used so far. Lacks a default function but, if you leave your stock standard neatly packed, it's a simply copy paste.
(2020-03-25) Waheed: soooooo gooooooooood
(2020-03-13) Віталій Шуманський: Супер! Просто, зрозуміло і працює відмінно!

(2019-03-28) Phillip Wesley-Brown: Would be great if it support jquery too :) But excellent as is for CSS/JS
(2019-03-07) Bania1988: Stopped to work correctly. Custom CSS vanishes after closing the popup, and opening it back. Every time I need to retype the custom CSS.
(2019-02-21) ࣭: Extremely useful for editing downright ugly sites you are forced to use or to highlight a specific part. Would love to easily export the injections I made to various sites in bulk instead of having to remember what sites I modified and copying from the little tab.
(2018-12-11) Robert Blue: This Chrome extension worked perfectly to get rid of an annoying "People also search for" box when using Google's Search feature. Thank you for this invaluable add-on.
(2018-08-24) Amit Sidhpura: Just Great! It will be great if I have someway to sync code, so we do not loose in future.
(2018-05-31) Csaba Együd: I use it to fix some annoying CSS issues in Gmail web interface. I'm amazed by it's smoothness. I haven't tried JS injection though, just CSS, but it's really potent. Great job!
(2018-05-31) Renzo Deils: Increíblemente útil y práctico.
(2018-05-28) Nur Waqid M: Berguna bagi front end @waqid
(2018-04-29) Sebastien Boureux: Très bien.
(2018-02-08) Tiby: Simple and effective.
(2018-02-08) Mihai D: It says it's compatible, but JS injection doesn't work on chromium, on ubuntu. After refresh only the first line of code remains.
(2018-02-08) Filip Poulsen: It deleted it when i close the tab, but its a very nice extension
(2018-01-22) Leslie Hernandez: Works perfectly! Very useful to me. Can you add an option to show the code/domain, written in the past?
(2018-01-16) Mozahidur Rahman: very useful!
(2018-01-10) Aizal Manan: The way it manage which website is easy. 5 star for that. And the CSS is live update (no need refresh). 5 star for that too. But I would like to edit in new tab for larger CSS/Script and to avoid the 1sec open popup delay
(2017-12-30) Công dân toàn cầu: Work well! However could it be show CSS and JS at the same time instead of tab? Or it would be so perfect if it have an option to setting what tab can be set as default/focus/active Thanks!
(2017-10-26) Brandon Reid: Love this. Works awesome! Thanks!
(2017-07-26) Jan Ruzicka: Very nice! But is it possible to make the plugin window larger? Like 1000x1000 at least? Thank you.
(2017-07-08) Matthew Fahrenbacher: Generally really good. There seems to be some kind of arbitrary character limit. Is there any reason why scripts are capped? Is this a setting that can be overriden somehow?
