Editing Pop-up ad (section)

===Circumventing pop-up blockers===

A ''hover ad'' or ''in-page pop-up'' uses [[JavaScript]] to combine a [[banner ad]], and a pop-up window that appears in front of the browser screen. JavaScript imposes an advertisement over a webpage in a transparent layer. This advertisement can appear in a variety of forms. For example, an advertisement can contain an animation that links to the advertiser's site. An advertisement can also look like a normal [[window (computing)|window]]. Pop-up blockers cannot block the ad because it is a part of the webpage, but it can be blocked with third-party ad blockers such as [[AdBlock]] and [[Adblock Plus]], or by using custom [[Cascading Style Sheets|style sheets]].
