Flash Ads are breaking web interfaces. Like this:
Actual screenshot from YouTube.
Ad networks need to simply set
“opaque” on flash embeds.
With more awareness, we can push ad networks to fix this issue.
It’s all about
wmode, a parameter that specifies
how a flash object is rendered on a webpage.
wmode needs to be explicitly set to
transparent. If it is not, no elements on the
webpage can go above the flash. EVER.
This is easy when you own the flash content, which is not the case for Flash Ads.
If the Flash Ad is not in an iframe. You can use FlashHeed to fix it.
WAIT, WHAT?! There is no fix??
Yep, that's right
So, I have to redesign my website’s UI in order to avoid this problem?
Yep, Google even suggests this. This is ludicrous in the 21st century web, which is brimming with dynamic overlaying UI elements. Google cannot expect site owners to redesign their site to accommodate these lazy Flash issues.
I heard that setting
wmode to anything other than
window causes performance issues.
Yes, that is true. However, we're talking about small simple Flash embeds, not fullscreen games with heavy animations. The average consumer these days have machines that are fast enough that Flash ads won't be a performance issue.
