This is generally CSS – depends on your theme and site.
That’d be a pretty specific plugin…
You want to change the background image on the entire site when you hover over a link?
its only for the homepage . i’ve a different sections and every section have its own background image , so at the homepage i show a four images for the four sections and when you hover over one images the background image will change of the homepage only
There’s no way to help with CSS without seeing the site.
Im still going to develop it so i want a tips where to search on that subject . it will be just four images in middle of screen and when you hover on one of them the background will change , i have seen that before on a website
see this tutorial/site – it goes over using image hovers on your site – gives you somewhere to start….
