Screen Options Not Working / Saving in WordPress Dashboard is a very irritating problem. Once you update / save any screen option and it doesn’t work at all. Or does only once and fails on next page reload.
When a page contains a large amount of content, the footer is pushed down off the viewport, and if you scroll down, the page ‘ends’ at the footer. However, If the page has small amount of content, the footer can sometimes ‘cling’ to the bottom of the content, floating halfway down the page, and leaving a blank space underneath, which looks ugly. So we need to make the footer stick to the bottom of page (not always fixed and visible).
While working with fancybox, you might have noticed that any button or link or input inside fancybox popup just behaves like previous/next item slider, making that coming item to appear in popup rather of doing it’s assigned code on click. All the reason is the width specified for `fancybox-nav` class with higher `z-index` for it.
In HTML, We need to hide and show the elements according to our requirement and we achieve this with different ways. An element could be hidden with “display:none”, “visibility:hidden” or “opacity:0”. But these options are used according to their requirement because their usage are different.
In jQuery and css, We hide and show the visibility of the element.We can use the functions .hide(), .show() or .toggle() or we can do it using css function also. How would we test if an element is visible or hidden using jQuery?
