2.1.47 [CSS-Level2-2009] Section 9.5.1, Positioning the float: the 'float' property

  • Article

V0073:

The specification states:

 None
  
 The box is not floated.

Quirks Mode and IE7 Mode (All Versions)

A line break is added after elements that are positioned by setting float to none.

V0074:

The specification states:

 3. The right outer edge of a left-floating box may not be to the right of the left 
 outer edge of any right-floating box that is to the right of it. Analogous rules 
 hold for right-floating elements.

Quirks Mode (All Versions)

The following variations apply:

  • Preventing the right outer edge of the left box from passing the left outer edge of the right box is not supported.

  • Preventing the left outer edge of the right box from passing the right outer edge of the left box is not supported.

V0207:

The specification states:

 [The float] property specifies whether a box should float to the left, right, or 
 not at all. It may be set for any element, but only applies to elements that 
 generate boxes that are not absolutely positioned.

Quirks Mode and IE7 Mode (All Versions)

The float property is incorrectly applied to absolutely positioned elements.

V0208:

The specification states:

 4. A floating box's outer top may not be higher than the top of its containing 
 block. When the float occurs between two collapsing margins, the float is 
 positioned as if it had an otherwise empty anonymous block parent taking part in 
 the flow. The position of such a parent is defined by the rules in the section on 
 margin collapsing.

Quirks Mode and IE7 Mode (All Versions)

A floated element that occurs between two margins that would otherwise collapse prevents the margin from collapsing.
