Use the Style Definition for Box panel to define settings for styles controlling the placement of elements on the page. See Style sheets overview and Editing a style.

To open the Style Definition dialog box, Choose Window > Styles and click Edit Style Sheet. In the dialog box that appears, choose a style and click Edit. Click the panel names on the left side of the dialog box. Leave any of the following attributes empty if they are not important to the style:

Width and Height determine the size of the element. Dreamweaver displays this attribute in the Document window only when it is applied to images or layers.

Float moves the element out of the page flow and places it at either the left or right page margin. Other elements wrap around the floating element as usual. Dreamweaver displays this attribute in the Document window only when it is applied to the IMG tag.

Clear defines on which sides of the element layers are not allowed. If a layer appears on the clear side, the element with the clear setting moves below it. Dreamweaver displays this attribute in the Document window only when it is applied to the IMG tag.

Padding defines the amount of space between the content of the element and its border (or its margin if there is no border). Dreamweaver does not display this attribute in the Document window.

Margin defines the amount of space between the border of the element (or the padding if there is no border) and any other element. Dreamweaver displays this attribute in the Document window only when it is applied to block level elements.
