Overview
In flash you can have text areas that are rendered as html. You can also apply formatting styles to this html. This will show a simple example on how to apply css to html text in flash. I’ll do a simple anchor tag style to show you the ropes. We’ll style a link to be underlined and then when you hover or mouse over it, we’ll change the color. It’s a design style that is widely used online in html, but flash doesn’t natively do it. As a matter of fact, flash doesn’t even natively underline links.
Steps
Import TextField.StyleSheet
create a style sheet object: var myCSS:StyleSheet = new StyleSheet();
Specify your styles: myCSS.setStyle(”a:link”, {color:’#0000CC’,textDecoration:’underline’});
Ensure that the text box is html enabled: myHTML.htmlText = myHTMLText;
Apply the style sheet object to your html text box: myHTML.styleSheet = myCSS;
Example
Actionscript
importTextField.StyleSheet;
myHTMLText = "
<h1>HTML Text (sample header)</h1>
Here is some <em>sample</em> <strong>html text</strong> "+
"filling a text box <a href="http://blog.circlecube.com">this link to circlecube</a> and example headers"+

Add this to the list of things I should have already known!
Story
I’ve got an html enabled text box and was trying to devise a way that I could have a hyperlink anchor tag not link to a webpage but actually do something flash. It didn’t seem possible, and I looked through all the different html css combinations I could think of. I finally resorted to trying to use some component like Deng or FlashML. FlashML had a smaller footprint and seemed to do more what I wanted, so I started investigating it. To my dismay, the support for it was few and far between. I found an older version that came with an example file and then a newer one with some documentation but no example and I found no examples any where else. So Lee, if you ever read this, some new examples could be nice. In the documentation I was reading about a functino called AddASFunction and the example html line was very interesting:
I started looking through the rest of the documentation to find this asfunction use. But all it had was:
The href attribute can include the asfunction string which allows the link provided by the anchor to call a function in Flash. More of this can be found within the addASFunction definition in this help document.
I knew I was on to something, asfunction. So a quick google search and I found the official doc! I was shocked that I had the tool to do this the whole time! Well, shocked and feeling like an idiot for never having heard of it before. I knew it could be done somehow, but had no idea that it was already a feature of htmlText in flash! So now that you know my embarrassing story, I’ll let you in on the secret.
Overview
In flash, you can allow html text within a text area. You either set the text html property as true with actionscript (my_txt.html = true;) or click the ‘Render text as HTML’ button in the properties window of the text area. You cannot enable html text on static text areas however. You can have links and various html elements (but not full html). Usually links have a url in the href attribut of the anchor tag, but flash will read a special value of ‘asfunction’ which specifies that an actionscript function is to be called rather than a url. The correct syntax is asfunction followed by a colon and then the name of the actionscript function to be called, optionally followed by a comma and a possible single argument to be passed to the specified function (href=”asfunction:functionName,argument”).
Steps
Enable html in the text box.
Have your function (ex: functionName) ready to be called from the html link.
Give the href attribute of the anchor tag a property “asfunction:functionName,argument” Notice that the official documentation calls for spaces after punctuation, but any space you put after the colon (:) or comma (,) will be sent to the function in the argument, or will expect a space in the function name and give you a headache.
Example
In this example I’ve got an html enabled text box with 4 links. The first is a standard link (I hope you know what that does). The next link calls an actionscript function with asfunction. The third link sends a single argument to another function. And the last link sends multiple arguments to yet another function. Wait! Multiple arguments? I thought I said only one was supported, well this example shows how to send multiple arguments disguised as a single param and parse them. It’s pretty simple actually.
Actionscript
importTextField.StyleSheet;
myHTMLText = "Sample text in an html enabled text box. "+
"Here's a normal link to <a href='http://blog.circlecube.com' target='_blank'>circlecube</a>! "+
"And some more links that don't go anywhere, they call functions in actionscript. "+
"<a href='asfunction:clickLink'>Click this one</a>, "+
"to see the actionscript function called from the html text box. "+
"<a href='asfunction:clickWithArg,Click this too'>Click this too</a>, "+
"and see that the actionscript function you're calling can have an argument passed to it. And "+
"<a href='asfunction:clickWithMultipleArgs, one,two,three args'>click me three and four</a> "+
"to see a way to send multiple arguments from your htmlText. "+
"Also, one last example of what not to do "+
"<a href='asfunction: clickWithArg, arg with preceding space'>Click for nothing</a>";

Intro to CSS
We use css to apply styles to certain elements on the page, we can target any div like this:
HTML
<div>Text</div>
CSS
div {
css-property: value;
}
Any class selector <div class=”divClass”> like this:
HTML
<divclass="divClass">Text</div>
with this:
CSS
div.divClass{
css-property: value;
}
<!-- or simply -->
.divClass{
css-property: value;
}
or any id selector, <div id=”divID”> like this:
HTML
<divid="divID">Text</div>
with this:
CSS
div#divID{
css-property: value;
}
<!-- or simply -->
#divID{
css-property: value;
}
These are the basics of css. Use an element tag name to target it, use a dot to access class names and a hash (#) to represent id names. A lot can be done with just that, but sometimes you may want to access something differently, an option is to use attribute selection.
Overview
More advanced we can apply styles to elements based on their attributes. Attribute selectors use the attributes of the tag.
We can use attribute selection to specify certain elements to stylize. For example if we have a page with many images but only certain ones have title attributes, which we want to stand out more, this css rule would do the trick:
CSS
img [title]{
border: 2pxsolid#000000;
}
It would cause any image with a title tag (no matter what the value of the title tag is) to have a 2px wide solid black border, such as <img title=”MyImage” src=”/images/sample.jpg” /> or <img title=”" src=”/images/sample.jpg” /> but not <img src=”/images/sample.jpg” /> because it has no title attribute.
Further we can specify which values of the title attribute we want to target. If we want to stylizee links to a certain site we can do this: a[href="http://blog.circlecube.com"] { }
CSS
a[href="http://blog.circlecube.com"]{
background-color: #EBEBEB;
}
it would style <a href=”http://blog.circlecube.com”>This link</a> but not <a href=”http://blog.circlecube.com/2008/05/21/”>this one</a> because it is not an exact match, nor <a href=”http://www.google.com”>this one</a> because it isn’t a match either, or at all.
For another example, if we want to stylize local links differently than absolute links, we’d want to look at the beginning of the attribute’s value only so we’d use ‘^=’. We could have something like this:
a[href^="http://"], a[href^="https://"] {
background: url(/images/external.gif) no-repeat right center;
padding-right:20px;
}
it would style <a href=”http://www.google.com”>This link</a> because it begins with ‘http://’ but not <a href=”/2008/05/21/”>this one</a> because it is does not begin with ‘http://’. But it would also style <a href=”https://paypal.com”>this</a> because it matches the selector after the comma ‘https://’, and even <a href=”http://blog.circlecube.com/2008/05/21/”>this</a> will be styled, because the link is absolute (even though it is local) so be careful with how you use it.

Here’s a new site and series from StomperNet called Going Natural 3!
It’s a bit of free videos made and released to showcase the talents and business of what StomperNet is about and what they do for their clients. They’re ‘moving the freeline’ so to speak…
The first video series begins with Dan Thies talking about his ‘Crazy Theory’ for AdWords.
This site contains the latest flash video player built by yours truly. I also did the design of the site: involving html, css, php, javascript and dealing with drupal too!

Overview:
Using what I learned with the Actionscript Javascript Communication Tutorial, and pushing it a little further I’ve set up this example of how flash renders html and css. This is basically a wysiwyg (What you see is what you get) html editor! Natively flash only handles some html and css. Many people have enhanced it’s capabilities with projects and Classes, but I made this to show what is accepted by default as far as html and css is concerned. I know there are specs and many lists about what will work, but to me the best way to know if my code will work is to try and see…
I’ve made this app so if I have a question, I just paste in my html/css and send it to the swf to see it rendered live. This saved me a few headaches, so I thought other might enjoy it as well… So here it is.
Example:
Render your own html and or css in flash. htmlToFlash.html
Here is the flash rendering of some dummy text as html with css applied
Here’s the html interface where I paste in the html and css.
Each supported css property has a corresponding actionscript property, but the naming convention is a little different for css in actionscript. Each actionscript property name is derived from the corresponding CSS property name; the hyphen is omitted and the subsequent character is capitalized. So for example: ‘font-weight’ becomes ‘fontWeight’.

About dot Stompernet dot Com (about.stompernet.com) is the new public (free) website from StomperNet. I helped implement this design and had to learn all about themes in Drupal. It’s still in beta, but it’s well on it’s way. It is an agglomeration site, where all the StomperNet Faculty’s feeds can be found and various other free content, like video in the Squambido player, and the Scrutinizer software.

The Overview:
An interactive navigation bar using CSS with rounded corners. Just put the html as an unordered list and your navigation links as list items and the CSS will do the rest! As shown here! The css will tell the browser to display this special unordered list as the menu. This utilizes a technique to have one background image with three states: normal, hover and active. The css controls the placement of the background image so when you hover, the images is displaced to show only the hover state, and likewise for the active and then returns to the normal state. This is compatible in all the browsers I have checked so far, let me know if you find any issues [thanks].
The Steps:
1. First make the html. An <ul> full of <li> elements.
2. Make the desired backgrounds. Three part background (or two) . One part ‘Normal’ state and another ‘hover’ state and optionally an ‘active’ state. Add additional backgrounds if you want anything like rounded corners, or just a header.
