CSS Round Boxes
Rounder corners can be created independently using the four individual border-*-radius properties (border-bottom-left-radius, border-top-left-radius, etc.) or for all four corners simultaneously using the border-radius shorthand property.
The border-*-radius properties can each accept either one or two values, expressed as a length or a percentage (percentages refer to the corresponding dimensions of the border box).
The Syntax: border-*-*-radius: [ <length> | <%> ] [ <length> | <%> ]?
Examples:
border-top-left-radius: 10px 5px;
border-bottom-right-radius: 10% 5%;
border-top-right-radius: 10px;
Where two values are supplied these are used to define, in order, the horizontal and vertical radii of a quarter ellipse, which in turn determines the curvature of the corner of the outer border edge.
Where only one value is supplied, this is used to define both the horizontal and vertical radii equally. If either value is zero, the corner will be square, not round.
border-radius
The border-radius shorthand property can be used to define all four corners simultaneously. The property accepts either one or two sets of values, each consisting of one to four lengths or percentages.
The Syntax: [ <length> | <percentage> ]{1,4} [ / [ <length> | <percentage> ]{1,4} ]?
Examples:
border-radius: 5px 10px 5px 10px / 10px 5px 10px 5px;
border-radius: 5px;
border-radius: 5px 10px / 10px;
The first set of (1-4) values define the horizontal radii for all four corners. An optional second set of values, preceded by a ‘/’, define the vertical radii for all four corners. If only one set of values are supplied, these are used to determine both the vertical and horizontal equally.
For each set of values the following applies:
If all four values are supplied, these represent the top-left, top-right, bottom-right and bottom-left radii respectively. If bottom-left is omitted it is the same as top-right, if bottom-right is omitted it is the same as top-left, and if only one value is supplied it is used to set all four radii equally.
Round Border Style Examples
Please copy and past the codes from the relevant box, edit the areas required, i.e. colors, padiing etc and paste them into your stylesheet. Then they will be available from your style drop down selector in the CMS Editor.
