Attribute	Values	Description	Use?
background	color size percentage pos-key-term url repeat repeat-x repeat-y no-repeat fixed scroll	Allows you to set all values of the background in one declaration. We recommend that you instead use the specific background-attributes.
background-attachment	fixed scroll	Dictate whether your background will scroll or not when the visitor scrolls the web page up and down.
background-color	color none	Allows you to set the color of the background.
background-image	url	Use an image as a background. Remember to choose an image that does not interfere with a visitor's ability to read your text.
background-position	size percentage pos-key-term	Define the position of your background image. You must define a background-image to use background-position.
background-repeat	repeat repeat-x repeat-y no-repeat	Dictate if and in which direction your background image will repeat. Vertically is the x-axis and horizontally is the y-axis.
border	solid double groove dotted dashed inset outset ridge hidden four-sides width-key-term	There are endless types of border styles at your disposal. We recommend that you experiement with many color/border-style combinations to get an idea of all the different looks you can create.
border-bottom	size color width-key-term	Set the bottom border of the element. If you would like to place a border on only one side of an HTML element, or maybe have a unique look for each side of the border, then use border-(direction).

clear	left right both	Specify which side may not have a floating element. If an element is already floating to the chosen side, then the current item will be displayed on the following line. Use "both" to clear both left and right.
color	color	Define the color of your font.
display	block inline	Control whether or not multiple elements can appear on one line. A paragraph tag only allows for one paragraph per line, by default. With CSS you can make new lines occur after each element (block) or prevent new lines (inline).
float	left right	Float an element to the left or right. The content will wrap around an element that is floated.
font-family	font-name	Font family's can be divided into two groups: serif and san serif. A san serif font does not include the small lines at the end of characters, while a serif font does include these small lines. When choosing which kind you prefer, remember that studies have shown that sans serif fonts are much easier to read on a computer monitor as opposed to a serif font.
font-size	percentage size fsize-key-term	Set the size of your font in a variety of ways. We recommend that you use percentages for general content and reserve static values for special cases.
font-style	italic oblique normal	Make your font italic, if it is supported by that font. This has a similar effect as the italic HTML tag.
font-variant	small-caps	Convert the font to small capitals. Note: not all fonts support this kind of style.
font-weight	weight-key-term weight-value	Control the thickness of your font. When using numerical values for font-weight, we suggest multiples of 100 (e.g. 200, 300, etc) because any less and you probably will not see any difference. The values range from 100(thin)-900(thick).
height	size auto	Set the height of an element.
letter-spacing	size	Specify the exact value of the spacing between your letters. Letter-spacing works best when pixels are used to define the spacing.
line-height	size percentage	Sets the height of the lines of text in an element.
list-style	circle square disc upper-alpha lower-alpha upper-roman lower-roman decimal inside outside url none	Define all attributes of a list element in one decleration. A useful technique is to define a style-type in addition to a list-image. If an image is not able to be loaded, then the style-type will be used as a backup.
list-style-image	url	Insert an image in place of the normal list styled bullets. A good choice for a bullet image would one that is smaller than the height of your text and is a relatively simple/plain graphic.
list-style-position	inside outside	Alter the indentation of your bullets or numbering systems. You may only use keyterms when specifying the indentation. Note: "outside" is actually the default setting for list indentation.
list-style-type	circle square disc upper-alpha lower-alpha upper-roman lower-roman decimal	Select the style for your list items. Numbering styles should be used with order lists, while shapes are best saved for unordered lists.
margin	size percentage auto	Define the margin of an element with this general attribute. A margin defines the space around an element's border. We have added borders to the example so that you may see the changes in the margin more readily.
margin-bottom	size percentage auto	It is possible to define individual margins by adding a direction suffix to the margin general attribute. Margin-bottom will set the bottom margin for this element.
margin-left	size percentage auto	It is possible to define individual margins by adding a direction suffix to the margin general attribute. Margin-left will set the left margin for this element.
margin-right	size percentage auto	It is possible to define individual margins by adding a direction suffix to the margin general attribute. Margin-right will set the right margin for this element.
margin-top	size percentage auto	It is possible to define individual margins by adding a direction suffix to the margin general attribute. Margin-top will set the top margin for this element.
padding	size percentage four-sides	Define the padding of an element with this general attribute. A padding is the space between an element's border and the content within it. We have added borders to the example so that you may see the effects of padding more readily.
padding-bottom	size percentage	It is possible to define these individual paddings simply by adding a direction suffix to the padding attribute. Padding-bottom will set the bottom padding for this element.
padding-left	size percentage	It is possible to define these individual paddings simply by adding a direction suffix to the padding attribute. Padding-left will set the left padding for this element.
padding-right	size percentage	It is possible to define these individual paddings simply by adding a direction suffix to the padding attribute. Padding-right will set the right padding for this element.
padding-top	size percentage	It is possible to define these individual paddings simply by adding a direction suffix to the padding attribute. Padding-top will set the top padding for this element.
position	absolute relative percentage size	Manipulate the exact position of your HTML elements. The Top and Left attributes define where the object will be placed. Move Left - Use a negative value for left. Move Right - Use a positive value for left. Move Up - Use a negative value for top. Move Down - Use a positive value for top.
text-align	right center left justify	Manipulate the alignment of your text.
text-decoration	line-through overline underline none	Manipulate the text's decoration. Note: to specify no text decoration, be sure that you use "none". Anchor underlines can be removed with that method.
text-indent	size percentage	Indent the first line of an element. This is most useful for indentation on paragraphs.
text-transform	capitalize lowercase uppercase	Modify the capitalization of your text with text-transform. Note: When someone copies and pastes text from your web site with CSS altered capitalization, they will paste the original, unaltered text that appears in your HTML code.
vertical-align	vertical-values	Sets the vertical alignment of your element, most often text. Vertical-align aligns the content that appears in an imaginary line. Examples of these lines are along a line of text or within a <td> of a table.
white-space	nowrap	Prevent your text from wrapping with nowrap. A new line will not be started unless you explicitly tell the browser to with <br/>. Note: we have defined the overflow and width CSS attributes, so that you may see nowrap in action.
width	size percentage auto	Set the width of an element.
word-spacing	size	Specify the exact value of the spacing between your words. Word-spacing works best when pixels are used as the spacing value.
z-index	whole-number	Set the z-index of an HTML element. The HTML element with the largest z-index will appear on top of those with a smaller z-index. z-index is useful for when using positioning and for resolving positioning conflicts.
