User Agent Stylesheet Overriding My Table Style? Twitter Bootstrap

User agent stylesheet overriding my table style? Twitter Bootstrap

I actually figured this out myself. I had the <!DOCTYPE html> tag wrongly written. So if you have this problem make sure the doctype declaration is correct!

user agent stylesheet override my own styles

The answer to the general question is that only property settings set on an element itself are taken into account when deciding which style setting “wins”. For example, if we have just one style sheet that sets font-size: 18px on the body element and another style sheet that set font-size: 9px on all p elements, then the font size of p elements is 9px, no matter what the origins of the style sheets are, e.g. whether the latter is just a browser default style sheet. Inheritance plays no role here. This is all described in section Assigning property values, Cascading, and Inheritance of the CSS 2.1 spec.

Inheritance is considered only after the above “fight” has been resolved. Only then are inheritable properties inherited by elements that have them not set at all.

The specific question does not provide specific code, but it can be inferred that you have something like this:

 <style>
   body { font-size: 12px; }
 </style>
 <table>
   <tr><td>foo
 </table>
 bar

Normally this causes both “foo” and “bar” to appear in 12px size. The table cell inherits the size from the table row, which inherits it from the tbody element, which inherits it from the table, which inherits it from the body.

However, in your case, this chain is broken. The reason is that the browser style sheet has

 table { font-size: medium }

which in practice tends to mean 16px. Now the table element has the property set, so the cell inherits that value.

Browsers do not normally have such a rule in their style sheets. However, in Quirks Mode, most browsers apply the rule. This means that font size is not inherited from body into tables. This reflects bugs (or oddities) in very old versions of IE and lets legacy page be rendered as they used to be.

If you have unintentionally caused Quirks Mode and do not need it for other purposes, just slap

<!DOCTYPE html>

at the very start of your document. But beware that old pages may get messed up in different ways, if they have been designed in testing conditions that correspond to Quirks Mode.

Alternatively, add the following rule into your style sheet:

table { font-size: 100% }

This means that a table gets the font size of its parent. (Like in inheritance, but safer.)

How to stop user agent stylesheets from overriding my css

The "problem" here is that there is actually no input style in the author stylesheet (see the spec for more info), and therefore the style that is defined in the user agent stylesheet is used.

The (relevant) user agent rule (on chrome) is:

input, input[type="password"], input[type="search"] {
   cursor: auto;
}

You can achieve what you want in a couple ways:

Create a css class that selects the input directly, for example
- using another css class, or
- selecting the input within the already-defined class,
- etc
Explicitly setting inheritance behavior for the cursor style on all inputs

For (1):

<style>
  .a, .a input {
      cursor: pointer;
  }
</style>

For (2):

<style>
  input {
      cursor: inherit;
  }
  .a {
      cursor: pointer;
  }
</style>

User agent stylesheet overwriting site styles

Anchors have a higher priority than any of the container elements (divs, spans, etc...), say .nav is your container element and you've set the color to gray, the color of anchors would still be the default blueish, since it has a higher priority. To overcome this, you need to define for example .nav a or even the sitewide a in your basic.css file.

EDIT

According to your new edit, you need to define footer a.

Display property overridden by User Agent Stylesheet

Css:

.hidden {    
    display: none
}

is the correct syntax.

What is a user agent stylesheet?

What are the target browsers? Different browsers set different default CSS rules. Try including a CSS reset, such as the meyerweb CSS reset or normalize.css, to remove those defaults. Google "CSS reset vs normalize" to see the differences.
