Updating the CSS to prepare for animated captions

Video: Updating the CSS to prepare for animated captions

Now to begin modifying our course we're going to take the index.html file and open this up in Dreamweaver. Now this course is also being offered as a code only course using Aptana Studio, so if you'd rather follow along in a code only format you can find the same course in the lynda.com Library. Now inside of Dreamweaver when I have the index.html file opened across the top here I can see all of the related files to this particular HTML file. So these are all of the CSS and JavaScript files that are being linked in to this particular HTML file. So I'm going to start by going to video_gallery.css.

Updating the CSS to prepare for animated captions

Now to begin modifying our course we're going to take the index.html file and open this up in Dreamweaver. Now this course is also being offered as a code only course using Aptana Studio, so if you'd rather follow along in a code only format you can find the same course in the lynda.com Library. Now inside of Dreamweaver when I have the index.html file opened across the top here I can see all of the related files to this particular HTML file. So these are all of the CSS and JavaScript files that are being linked in to this particular HTML file. So I'm going to start by going to video_gallery.css.

Let's click on this item, let's switch to Code only view and in here we want to make one change that Dreamweaver will let us change in the CSS only in Code view not in the WYSIWYG environment. So inside of the a. videoLink img.play after left: 75, let's hit a space, we're going to type opacity: .5;. What this is going to do is take those Play icons that are semitransparent PNG files and make them have the transparency again.

So again this is one of those things in the introduction video that won't work in IE 7 or 8. So if you're concerned about how this looks in IE 7 and 8 then don't make this particular change. Once we've done that let's switch back out to Design view. Inside of Design view under the CSS Styles panel under video_gallery.css, let's scroll down, let's edit the CSS rule that says a.videoLink div.caption. Inside of here we're going to make a few changes. First, let's come over to the Box Properties. Let's change the Width to 165.

For the Padding we're going to set a Top and Right of 20, Bottom of 15, Left of 15, and then let's go to the Position settings and let's take the Bottom value of 0 and set that to null and for the Top value let's set that to 116. What this is going to do is take the caption div that's inside of the anchor link with the videoLink class and move the caption down to 116. Now since those thumbnails are only 115 pixels tall there going to be one pixel outside of the viewable area. Let's click OK.

Let's come up to a.videoLink, let's make one change inside of here. Let's come down to Positioning, let's come over to Overflow and set that value to hidden. So that way those divs holding the captions that are outside of the bounding area of the anchor link with the videoLink class will be hidden or masked from view. Let's click OK. Let's come up to Live view and now inside of the Live view I can see all the icons are semitransparent and the captions while still on the page are actually below the actual thumbnail areas and they're being masked up by the fact that we set the a.videoLink class to an Overflow of hidden.

Now that we've our CSS modified, in the next movie we'll modify the JavaScript to actually animate those captions back up once we actually roll over these individual thumbnails.
