Using
CSS Styles: Page 3

If you stumbled upon this page without having completed the previous page, do take a few moments to catch-up with us. Click here to return to the previous page. For everyone else, let's continue to learn about CSS in Flash.

As much as I would like to, I am not good enough with CSS to explain how to use it. Instead, the following site should help you out tremendously: http://www.htmlgoodies.com/beyond/css.html I will explain how to use CSS within Flash and any extra tricks you may like.

The CSS File
 In the ActionScript, no doubt I'm sure you noticed that a file called flash.css was being loaded from a location on the server. Well, without further delay, here is the content of the flash.css file:

[ CSS file created in DreamWeaver MX 2004 ]
 

If you were the further analyze the HTML text in the variable quick, you will see a sentence that starts and ends like this:

<p class='one'>The quick Kirupa jumps over the lazy dog.</p>

Notice that the above sentence is formatted with the style "one" taken from the CSS file. If you were to replace the text one with something like four, you will notice that the text in your animation absorbs the characteristics defined by the four style in the CSS file. Also, if you were to remove the <p> tags altogether, the format of the text will be what you manually define in the Properties Panel for the text panel.

While CSS has numerous properties that it can modify for various elements beyond text, the current implementation of CSS in Flash is quite limited. The following table, copied from the Flash MX 2004 ActionScript dictionary, shows the tags Flash MX 2004 supports and interprets:

CSS ActionScript Usage and supported values
text-align textAlign Recognized values are left, center, and right.
font-size fontSize Only the numeric part of the value is used; units (px, pt) are not parsed; pixels and points are equivalent.
text-decoration textDecoration Recognized values are none and underline.
margin-left marginLeft Only the numeric part of the value is used. Units (px, pt) are not parsed; pixels and points are equivalent.
margin-right marginRight Only the numeric part of the value is used. Units (px, pt) are not parsed; pixels and points are equivalent.
font-weight fontWeight Recognized values are normal and bold.
font-style fontStyle Recognized values are normal and italic.
text-indent textIndent Only the numeric part of the value is used. Units (px, pt) are not parsed; pixels and points are equivalent.
font-family fontFamily A comma-separated list of fonts to use, in descending order of desirability. Any font family name can be used. If you specify a generic font name, it will be converted to an appropriate device font. The following font conversions are available: mono is converted to _typewriter, sans-serif is converted to _sans, and serif is converted to _serif.
color color Only hexadecimal color values are supported. Named colors (like blue) are not supported.
display display Supported values are inline, block, and none.

While the above list contains many of the tags you would probably use, you should be aware that when using a third-party program like DreamWeaver to create the CSS tags, several of the tags will simply be ignored by Flash. So, if your CSS file includes a line for text background-color, Flash will simply skip that line and apply the above properties that it does understand.


With that table, you have reached the end of this tutorial for now. As new updates and revisions occur, I will be sure to drop a line on the home page to inform you of that festive occasion. CSS is really useful for Flash sites that want to convey a lot of information, and now you have the ability to easily implement CSS styles using nothing more than a simple style sheet.
