Nosto can add entirely new placements or manipulate existing elements of a web page upon page load.
To achieve this, you need to define the relevant css selectors of the elements you want to target. Once defined, you need to choose which method you want to use to manipulate the elements. Nosto supports before, after, insert as first, insert as last and replace.
If you want the manipulation of an element to happen only on a given page or multiple pages, you can apply a restriction using the URL Rules input field.
