浏览器的HTML元素的默认CSS [英] Browsers' default CSS for HTML elements

问题描述

我在哪里可以找到HTML元素的浏览器默认CSS？

许多HTML元素都有一些默认的CSS属性，在未知/不需要的行为。例如，输入框在不同的浏览器中显示不同。我正在寻找一个涵盖新的CSS3属性和新的HTML5元素的地方。

我在其他问题（例如浏览器的默认CSS样式表）答案建议CSS重置的解决方案。这个解决方案有时是不需要的，通常我实际上想保留一些基本属性（如在Chrome中突出显示输入框）。换句话说：我不想因为我不知道他们做什么而摆脱某些东西。

因此， strong>是否有一个网站可以给我所有这些信息（或者也许是最多的）？

解决方案

• Firefox（Gecko）： https://dxr.mozilla.org/mozilla-central/source/layout/style/res/html.css 。或者，浏览到 resource：// gre-resources / 并查看 html.css 。


• Chrome / Safari（WebKit）： http://trac.webkit.org/browser/trunk/Source/WebCore/css/html.css
  
  
  
  
  • Chrome（ Blink）： https://chromium.googlesource.com /chromium/blink/+/master/Source/core/css/html.css
  
  


• Internet Explorer （Trident），旧版本： http://www.iecss.com/

根据robertc的建议，您还可以查看HTML5 Boilerplate样式表，它标准化很多东西的显示，而不是传统意义上的重置。它还修复了很多错误/不一致。

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)?

解决方案

It's different for each browser, so:

• Firefox (Gecko): https://dxr.mozilla.org/mozilla-central/source/layout/style/res/html.css. Or, browse to resource://gre-resources/ and look at html.css.
• Chrome/Safari (WebKit): http://trac.webkit.org/browser/trunk/Source/WebCore/css/html.css
  • Chrome (Blink): https://chromium.googlesource.com/chromium/blink/+/master/Source/core/css/html.css
• Internet Explorer (Trident), older versions: http://www.iecss.com/

As suggested by robertc, 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.
