CSS reset that sets everything to default values

Question

I\'m working on a browser extension that adds it\'s UI to the pages DOM. On some pages I have the problem certain styles affect my UI. To counter this I keep my UI underneat

Answer 1

I recommend using a quick Google search to find something like so: http://meyerweb.com/eric/tools/css/reset/

You can implement the reset in as-is and then if any problems arise down the road, simply add to it as needed.

Be aware that some pre-made CSS resets require a shout-out to using them.

Answer 2

Yes, absolutely.

There are two schools of thought to this. One is the zeroing style reset sheets, which basically remove all margin, padding and other such settings from the css. A good example of this is Eric Meyer's Reset CSS

The other approach is to set everything to roughly what you'd sensibly expect it to be, setting a reasonably looking margin to paragraphs and headings, indenting lists etc. A good example of this is Normalize.css

Some browsers also support the initial value, which sets the value of a property back to what it intially was. It's not widely supported enough to use in production, IMO.

Answer 3

As you are applying your styles to different pages with different unique styles, its hard to say if you will get success on removing all styles from all pages with some CSS reset.

But maybe these can help:

Normalize.css (used by many CSS frameworks)

CSS Reset by Meyer

Answer 4

1. Eric Meyer’s “Reset CSS” 2.0
   _{(the original one)}

2. HTML5 Doctor CSS Reset
   _{(extends the Eric Meyer's one to improve HTML5 tags reset)}

3. Yahoo! (YUI 3) Reset CSS
   _{(based on Normalize.css)}

4. Universal Selector ‘*’ Reset

5. Normalize.css 1.0 2.1.3
   _{("…as used by Twitter Bootstrap, HTML5 Boilerplate, YUI 3, Pure, TweetDeck, Soundcloud, Medium, NASA, GOV.UK, Guardian, Rdio, Favstar, iA, and many others.")}

There are others, but this were (and still are) the 2012’s most popular CSS Reset scripts.

Answer 5

I have come across the same problem. The usual CSS normalizers listed by the other answers does not answer the question because it is made to cancel the differences across the browser's default styles.

In the context of an extension, I needed to cancel every specific style that may exist on a random website.

I have come across this solution (I am not sure if it was possible at the time of the question, 7 years ago).

.your-container-class,
.your-container-class *,
.your-container-class *::before,
.your-container-class *::after {
    all: initial;
}

So far it seems to achieve the goal by removing the differences across websites. The downside is that it resets even some default styles (ol, ul, li not behaving like lists for example).

Answer 6

Html5 boilerplate has an normalize.css which sets al lot of css styles to a default. http://html5boilerplate.com/
