Kill sticky headers: a bookmarklet to get rid of the web's static blobs

Alisdair McDiarmid's Kill Sticky Headers bookmarklet banishes all fixed-position CSS elements, like navigation bars, cookie consent popups, email list subscription solicitations, and so on — these are an annoyance at best and an accessibility problem at worst; if you have low vision like me and habitually scale up the type on the pages you browse, these elements grow to completely eclipse the type, making you choose between eyestrain and access. Drag this Kill Sticky to your toolbar and click it whenever you want to get rid of these annoyances.
