# How to hide the Google IMA UI on Web

You may want to know which controls are visible to the viewer during ads, so you can use your own UI elements instead.

Unfortunately Google IMA provides very limited control over the UI. The only thing that you can change or hide from THEOplayer is the countdown: to do so, set `showCountdown` to `false` in your [`AdsConfiguration`](https://docs-preview.optiview.dolby.com/pr-863/theoplayer/v11/api-reference/web/interfaces/AdsConfiguration#showCountdown).

Using other methods, like CSS or JavaScript, to modify the Google IMA UI elements styles will also not work due to:

* the usual higher specificity of the *iframe* CSS
* the security restrictions on XSS.
