How To Style Table Cells?
Margin, Border and Padding are difficult to apply to inline elements. Officially, the <TD> tag is a block level element because it can contain other block level elements (see Basics - Elements).
If you need to set special margins, borders, or padding inside a table cell, then use this markup
<td>
yourtext </div></td>
to apply the CSS rules to the div inside the cell. </p>
How To Style Forms?
Forms and form elements like SELECT, INPUT etc. can be styled with CSS - partially.
Checkboxes and Radiobuttons do not yet accept styles, and Netscape 4.xx has certain issues, but here is a tutorial that explains the application of CSS Styles on Form Elements.
Why Does My Content Shift To The Left On Some Pages (in Ff)?
That'll be the pages with more content? The ones that have a vertical scrollbar? If you look in IE there's probably a white space on the right where there would be a scrollbar if there were enough content to require one. In Firefox, the scrollbar appears when it's needed and the viewport becomes about 20px smaller, so the content seems to shift to the left when you move from a page with little content to one with lots of content. It's not a bug or something that needs to be fixed, but it does confuse and irritate some developers.
If, for some reason, you'd like Firefox to always have scrollbars - whether they're needed or not - you can do this
CSS html {
height:100.1%;
}
How Do I Combine Multiple Sheets Into One?
To combine multiple/partial style sheets into one set the TITLE attribute taking one and the same value to the LINK element. The combined style will apply as a preferred style, e.g.
<LINK REL=Stylesheet HREF="default.css" TITLE="combined">
<LINK REL=Stylesheet HREF="fonts.css" TITLE="combined">
<LINK REL=Stylesheet HREF="tables.css" TITLE="combined">
Which Set Of Definitions, Html Attributes Or Css Properties, Take Precedence?
CSS properties take precedence over HTML attributes. If both are specified, HTML attributes will be displayed in browsers without CSS support but won't have any effect in browsers with CSS support.
Why Call The Subtended Angle A "pixel", Instead Of Something Else (e.g. "subangle")?
In most cases, a CSS pixel will be equal to a device pixel. But, as you point out, the definition of a CSS pixel will sometimes be different. For example, on a laser printer, one CSS pixel can be equal to 3x3 device pixels to avoid printing illegibly small text and images. I don't recall anyone ever proposing another name for it. Subangle? Personally, I think most people would prefer the pragmatic "px" to the non-intuitive "sa".
Why Was The Decision Made To Make Padding Apply Outside Of The Width Of A 'box', Rather Than Inside, Which Would Seem To Make More Sense?
It makes sense in some situations, but not in others. For example, when a child element is set to width: 100%, I don't think it should cover the padding of its parent. The box-sizing property in CSS3 addresses this issue. Ideally, the issue should have been addressed earlier, though.
Can Css Be Used With Other Than Html Documents?
Yes. CSS can be used with any ny structured document format. e.g. XML, however, the method of linking CSS with other document types has not been decided yet.
Can Style Sheets And Html Stylistic Elements Be Used In The Same Document?
Yes. Style Sheets will be ignored in browsers without CSS-support and HTML stylistic elements used.
How Do I Design For Backward Compatibility Using Style Sheets?
Existing HTML style methods (such as <font SIZE> and <b>) may be easily combined with style sheet specification methods. Browsers that do not understand style sheets will use the older HTML formatting methods, and style sheets specifications can control the appearance of these elements in browsers that support CSS1.
Why Use Style Sheets?
Style sheets allow a much greater degree of layout and display control than has ever been possible thus far in HTML. The amount of format coding necessary to control display characteristics can be greatly reduced through the use of external style sheets which can be used by a group of documents. Also, multiple style sheets can be integrated from different sources to form a cohesive tapestry of styles for a document. Style sheets are also backward compatible - They can be mixed with HTML styling elements and attributes so that older browsers can view content as intended.
What Is Css Rule 'at-rule'?
There are two types of CSS rules: ruleset and at-rule. At-rule is a rule that applies to the whole style sheet and not to a specific selector only (like in ruleset). They all begin with the @ symbol followed by a keyword made up of letters a-z, A-Z, digits 0-9, dashes and escaped characters, e.g. @import or @font-face.
What Is Selector?
CSS selector is equivalent of HTML element(s). It is a string identifying to which element(s) the corresponding declaration(s) will apply and as such the link between the HTML document and the style sheet.
For example in P {text-indent: 10pt} the selector is P and is called type selector as it matches all instances of this element type in the document.
in P, UL {text-indent: 10pt} the selector is P and UL (see grouping); in .class {text-indent: 10pt} the selector is .class (see class selector).
What Is Css Declaration?
CSS declaration is style attached to a specific selector. It consists of two parts; property which is equivalent of HTML attribute, e.g. text-indent: and value which is equivalent of HTML value, e.g. 10pt. NOTE: properties are always ended with a colon.
What Is 'important' Declaration?
Important declaration is a declaration with increased weight. Declaration with increased weight will override declarations with normal weight. If both reader's and author's style sheet contain statements with important declarations the author's declaration will override the reader's.
BODY {background: white ! important; color: black}
In the example above the background property has increased weight while the color property has normal.
What Is Cascade?
Cascade is a method of defining the weight (importance) of individual styling rules thus allowing conflicting rules to be sorted out should such rules apply to the same selector.
Declarations with increased weight take precedence over declaration with normal weight
P {color: white ! important} /* increased weight */
P (color: black} /* normal weight */
Are Style Sheets Case Sensitive?
No. Style sheets are case insensitive. Whatever is case insensitive in HTML is also case insensitive in CSS. However, parts that are not under control of CSS like font family names and URLs can be case sensitive - IMAGE.gif and image.gif is not the same file.
How Do I Have A Non-tiling (non-repeating) Background Image?
With CSS, you can use the background-repeat property. The background repeat can be included in the short hand background property, as in this example
body {
background: white url(example.gif) no-repeat ;
color: black ;
}
Styles Not Showing?
There are different ways to apply CSS to a HTML document with a stylesheet, and these different ways can be combined
* inline (internal) (Deprecated for XHTML)
* embedded (internal)
* linked (external) and
* @import (external)
Note: An external stylesheet is a text file that contains only CSS Styles. HTML comments are not supposed to be in there and can lead to misinterpretation (> is the CSS "Child" selector!).
