Finally identical inputs across different browsers and devices — both desktop and mobile.
iCheck is verified to work in Internet Explorer 6+, Firefox 2+, Opera 9+, Google Chrome and Safari browsers.
Mobile browsers (like Opera mini, Chrome mobile, Safari mobile, Android browser, Silk and others) are also supported. Tested on iOS (iPad, iPhone, iPod), Android, BlackBerry and Windows Phone devices.
We are getting closer to Boostrap 4 and I really love what we are getting with the first alpha version.

“This is a jQuery plugin which allows us to quickly check if an element is within the browsers visual viewport, regardless of the scroll position. If a user can see this element, the function will return true.”
“Simple jQuery plugin to determine if an element is within the viewport. Optional parameters allow the user to specify a minimum percentage of the element’s dimensions that must be visible to qualify.”
When using Fullpage.js, overflowing section / slide content will be made scrollable with Slimscroll. If you want to use addons that rely on the natural scroll event, these will fail with Slimscroll. One of the candidates breaking is Scrollreveal.js for example.
I decided to work around that, to allow animations to be triggered when elements become visible or invisible to the viewport.
You could code the viewport visibility check yourself or use the “visible” jquery plugin.

The idea was to extend or hook into slimscroll without touching the fullpage.js codebase. Fullpage.js wraps overflowing content within a fp-scrollable container. Slimscroll itself provides events to track your position within the scrollable area in pixels or when top / bottom have been reached.

This is just a crude and simple starting point, but should give you the basic idea. This still needs some throttling, so that its not called on every scroll position.

Hopefully Fullpage.js will be switching to iScroll natively in the future, as it provides far more options to handle scrollable areas. You can use iScroll now, but you have to disable the scrolling feature within Fullpage.js and call iScroll yourself. Not that difficult to do :)
There is also a WordPress Plugin that wraps Fullpage.js natively with a nice interface (WP_Fullpage) and my upcoming Visual Composer integration, which already uses iScroll :)
“Prism is a lightweight, extensible syntax highlighter, built with modern web standards in mind.”
“In iOS 7.1, a property, minimal-ui, has been added for the viewport meta tag key that allows minimizing the top and bottom bars in Safari as the page loads. While on a page using minimal-ui, tapping the top bar brings the bars back. Tapping back in the content dismisses them again. Brim is a view (minimal-ui) manager for iOS 8”
The timeout is cleared every time a resize event fires, making sure your code is only executed once the resizing actually stopped.
