How can you make an effect like on this site . There is a table of contents of the book, when you click on it increases. How can this be implemented? I downloaded scripts that are on that site, but nothing works.
If you mean a picture that increases when you click, you can either invent your “bike” on
js , or use some of the ready-made libraries, such as highslide .
To install this particular script, you need to attach a script to the page, styles and set the path to graphic elements - all this is well described on the site .
