[cl0] A 'p' element with browser-default 'line-height'. Its 'font-size' has been set to 15px, the same as the other tests in this page. This element is included largely for reference purposes, and is not intended to demonstrate a particular aspect of the CSS specification. Extra text has been added to this element for the sole purpose of making it more likely that the content will be rendered using two or more lines of text.

This is the end of the parent element.

[index page] [section] [Previous] [Next] [Specification This is the end of the 'cl3' content. Extra text has been added to this element for the sole purpose of making it more likely that the content will be rendered using two or more lines of text.

[cl4] This 'div' element should have a line-height of twice the font size, which should lead to a separation of 30 pixels between each baseline. Extra text has been added to this element for the sole purpose of making it more likely that the content will be rendered using two or more lines of text.
[shrink] This text should have a font-size two-thirds that of the parent element, and the separation between baselines should also be two-thirds the parent; in other words, 20 pixels. This happens because the value '2' is inherited as a "scaling factor" that is multiplied by the value of the element's 'font-size' (in this case, 10px * 2). Extra text has been added to this element for the sole purpose of making it more likely that the content will be rendered using two or more lines of text.
[grow] This text should have a font-size half again as large as that of the parent element, and the separation between baselines should also be half again that of the parent; in other words, 45 pixels. This happens because the value '2' is inherited as a "scaling factor" that is multiplied by the value of the element's 'font-size' (in this case, 22.5px * 2). Extra text has been added to this element for the sole purpose of making it more likely that the content will be rendered using two or more lines of text.
This is the end of the 'cl4' content. Extra text has been added to this element for the sole purpose of making it more likely that the content will be rendered using two or more lines of text.

[cl5] This 'p' element contains an inline element that is twice the size of the 'p' element's text, but it does not have an increased line-height. Thus, the inline element's content area will overlap other lines in the parent element. The inline element is [huge]. Note that the baselines of both the 'p' and the 'span' are aligned, since that's the default behavior. The overlap can go both upward and downward; that is, preceding and succeeding lines can be overlapped. The height of the line in which the 'span' appears may also be taller than normal due to the inline box of the 'span'.

[cl6] This 'p' element contains an inline element that is twice the size of the 'p' element's text, and which will inherit the scaling factor for its line-height. Thus, the inline element's content area will not overlap other lines in the parent element. The inline element is [huge]. Note that the line in which the inline element appears is increased in height to account for its presence. This does not increase the content area of the line of text, as the silver background demonstrates.

[cl5] This 'p' element contains an inline image that is twice the height of the 'p' element's text. Thus, the images will increase the height of the line in which it appears, and will not overlap content in lines above or below it. The inline element is test image. Note that the bottom of the 'img' is aligned with the baseline of the 'p', since that's the default behavior.

7. Centre aligning a block element

This tip seems almost precisely correct. The only improvement I might suggest is to use individual properties for 'auto' instead of the 'margin' shorthand. I have a vague recollection of a few browsers having problems (ignoring?) the margin: 0 auto; shorthand, whereas they worked fine with the margin-left:auto; margin-right:auto; longhand equivalent. If someone knows of the specific browser(s) that have this problem, please link to this post and point them out. Thanks.

Notes

  1. Opera (up to version 8.5) doesn't apply the :first-line pseudo-element when the mime-type of the document is application/xhtml+xml; hence, a test-case served as html 4.01 text/html.
  2. IE 5 Win doesn't apply the rules; IE 5.5 and IE 6 Win appear to understand the single and double column (:) notation. It is not clear if this by design or another twisted logic by this browser. I guess it simply ignores the first column when the double column notation is used. IE 5.x and 6: there are lots of inheritance problems with both selectors, particularly when used in combination with other selectors, see pseudo-CSS for some of them.
  3. Opera 7.54, 8, 8.5 are buggy with the :first-line pseudo-element. There are some strange inheritance effects. Opera 9 performs better, but appears the fictional box as a block-level element. All versions of Opera have problems with combined selectors (in E ::first-line, element is ignored or treated as universal selector.
  4. Most browsers tested, except Safari and Gecko are wrong in painting the background for the :first-line pseudo-element: they expand the height of the anonymous box representing the first-line to include the height of the line-box created by the first-letter box.
