Hi! Is it possible to place on sites Ucraft calculator widget from ucalc.pro/en and any other similar interactive widgets? Is it possible to insert the code on the site and is there any special instruction for this? Thank!
Open your web page in the Google Sites editor. Put the insertion point where you want the calculator to appear and click on Insert > More gadgets… Search for “include iframe”. Click on the Include gadget (iframe) in the list.
