Select a varying name id of an element for a custom style?

There's a website that puts ads in iframes with ids that change on reload. They also have anti addblock:

enter image description here I want to make a custom style using an extension that hides all the elements that have an id beginning with that "adsIframe". Is there any way to select all those elements?

    You can use the wildcard attribute selectors in CSS. For example:

    iframe[id^="adsIframe"] {
       color: red;

    Will select any iframe element whose id attribute begins with adsIframe. Using *= will target those whose id attribute contains adsIframe.

    From MSDN:

    Represents an element with an attribute name of attr whose value is prefixed (preceded) by value.
