2 border: repeat-y no-repeat 1px solid dashed dotted double /* needs at least 3px to see effect */ ridge /* regular 3d border needs at least 4px to see effect */ groove /* kind of strange, needs at least 4px to see effect */ inset /* like a recessed bevel */ outset /* like a button bevel */ # Example: div { border:2px solid #ffffff; } Browser Differences: borders are drawn INSIDE the container in IE, Opera 7. borders are drawn OUTSIDE the container in Firefox, Netscape 7, Safari. (part of the annoying "box model" conflict) border-collapse: border-top: collapse border-: border-bottom: border-: bottom: clear: 4px /* positions an object 4px up from the bottom of its container */ both clip: color: Clears a "floated" element. See also: float: rect(top bottom ) # /* #RRGGBB, each digit is 0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f */

5 decimal decimal-leading-zero lower-roman upper-roman lower-alpha upper-alpha lower-greek lower-alpha lower-latin upper-alpha upper-latin url(images/bullet.gif) margin: Note: If you want a custom bullet image, it works better this way: ul {margin:0; padding:0; list-style:;} li { margin:0 0 6px 0; padding: px; /* padding for bullet image */ background:transparent url(images/bullet.gif) no-repeat; } 0 /* to turn all margins off, no unit is necessary */ 4px /* use a single value for the same margin on all sides */ 2px 0 2px 0 /* specify separate top,, bottom, margins (clockwise from top) */ auto /* if AND are auto, element will be centered */ Margins add transparent space OUTSIDE the background and border. margin-top: Examples: img {margin:2px 0 2px 0;} div (margin: 4px auto 10px auto;} /* div will be horizontally centered */ margin-: margin-bottom: margin-: min-height: Not supported in IE so its fairly useless min-width: Not supported in IE so its fairly useless overflow: padding: visible hidden scroll auto

6 0 /* to turn all padding off, no unit is necessary */ 4px /* use a single unit for even padding on all sides */ 2px 0 2px 0 /* specify separate top,, bottom, padding (clockwise from top) */ Padding adds space INSIDE the background and border. padding-top: padding-: padding-bottom: padding-: position: : static /* where it would "ly" be in the html flow */ absolute /* position inside the parent element */ relative /* position relative to where it would "ly" be */ fixed /* do not scroll the element as the page scrolls */ 4px Positions an element from the -hand edge of its container. text-align: center justify /* makes even and margins, like a newspaper column */ text-decoration: underline overline line-through blink /* does not work in IE, only works in Firefox, Opera 7 */ text-transform: top: capitalize lowercase uppercase 4px vertical-align: baseline middle sub /* do not use, messes up line spacing, see below */ super /* do not use, messes up line spacing, see below */ text-top text-bottom

7 Making superscripts and subscripts without messing up the line spacing: CSS.sups {position:relative; top:-4px;}.subs {position:relative; top:4px;} visibility: HTML Here's a superscript1. hidden /* the element will still influence other elements on the page */ visible white-space: width: z-index: To remove the element completely, use display:; instead. nowrap /* do not wrap a line until a line break, somewhat buggy in some browsers */ pre /* like using <pre> in HTML, requires "strict" mode for IE 6 */ 200px 90% 5 /* a DIV with a z-index of 5 will be "above" those with 4 or lower */ Z-index only applies to other objects in the same container.
