Width and Height determine the size of the element. 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. 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.
Margin defines the amount of space between the border of the element and any other element.
Places a border around the selected object or text. Border attributes include width, style and color. Allows formatting of the type of bullet, a bullet image and placement of the bullet. Notice that Dreamweaver can insert the selected bullet graphic in a list for you. You can set the visibility of an object inside a layer to visible or hidden, can set z-index so that one image is behind or in front of another image.
