First I open the site in Safari, then click and drag the icon next to the URL (the favicon) to the Dock between the wastepaper basket and the divider which separates the program and non-program content.
A ‘spring-loaded’ folder (Apple calls them URL or @ icons) appears in the spot you selected. When the cursor moves near the folder its name appears. All the features of the page are available when the icon is clicked.
Perhaps after reading this someone will let me know if there is a similar function I can put on my wife’s iPad.
