Browsers' default CSS for HTML elements

Where can I find a browser's default CSS for HTML elements?

Many HTML elements come with some default CSS properties which can sometimes result in unknown/unwanted behaviour. For example Input boxes are displayed differently in different browsers. I'm looking for a place that covers the new CSS3 properties and the new HTML5 elements.

I've seen in other (much older) questions (such as Browsers' default CSS stylesheets) answers that suggest a solution of CSS reset. This solution is sometimes not wanted, often I would actually like to keep some of the basic properties (such as the highlighting of input boxes in Chrome). In other words: I don't want to get rid of things just because I don't know what they do.

So, Is there a site that can give me all this information (or perhaps most)?

It's different for each browser, so:

You can also look at the HTML5 Boilerplate stylesheet, which "normalizes the display of a lot of stuff without being a reset in the traditional sense". It also fixes quite a few bugs/inconsistencies.

It's also worth looking at: https://github.com/necolas/normalize.css/blob/master/normalize.css

While this is an old cross browser problem, as each browsers has his own rendering and behavior with some HTML elements like medias and inputs elements, we can now in 2017 use pretty safely the CSS filters property on top of them.

This allow to give a color palette with the hue-rotate filter that will render pretty well cross browsers.

The following snippets show a way to use a input type color to render this effect in realtime on a video element with javascript.

To use only CSS, this is mandatory to use each one of this filters: sepia not at 0, high saturation, grayscale at 0, high contrast, and then give a color with the hue-rotate property, following my tests. The invert filter isn't mandatory, but is giving some deep effects.

As well, the drop-shadow filter is working pretty nicely cross browser. To be use like this: filter:drop-shadow(2px 20px 50px red) [X,Y,RADIUS,COLOR]

function styloElem() {
  stylo.dataset.hue = ((parseInt(stylo.value.substring(1), 16))/46666).toFixed(0)
  
  media.style.cssText += ";filter:sepia(100%) saturate(1000%)grayscale(0)contrast(200%)hue-rotate("+ stylo.dataset.hue+"deg)invert("+(stylo.dataset.hue/3.6)+"%)"

}
styloElem()
body {
  text-align:center;
  background:#001;
  color: white
}
video {
  width:500px;max-width:500px
}
Colors: 
<input 
       type="color"
       id="stylo"
       oninput="styloElem()"
       class="media"
       data-hue="0" />

<br><br> 

<video 
       controls
       id="media"        
       onplay="this.removeAttribute('controls');this.style.all='unset'"     
       onpause="this.controls='controls';styloElem()"

No one has mentioned any source for the CSS defaults in Edge. I looked, and I couldn't find anything authoritative, but I found this stylesheet that looks plausible: https://gist.github.com/jonathantneal/abc52743caa0a019d359ec4ba2ce965b
