debug z-index and stacking context
View debug-zindex-stacking-context.js
* Paste this into your dev tools console (or even better as a snippet)
* It will parse the page and find all the things that create a new stacking context
and dump some info about them to the console. It will also outline them on the page.
* This is pretty rough and probably misses heaps of bugs and edge cases.

Handling Page Transitions on Single Page Web Apps


Real world application with a lot of pages (or "screens") have to deal with problem managing the pages' DOM and memory efficiently and at the same provide a nice smooth transition effect between pages. This is not a real problem when you do it in native apps since Android or iOS already handle the hard work for you, but when come to JavaScript, HTML, and CSS, running on mobile browsers, this is the real challenge.

There are 2 common approaches to solve this problem:

  • Approach 1: Keep all the pages in the DOM tree, use CSS (for example display) to transit between pages.

(function () {
String.prototype.padRight = function(l,c) {return this+Array(l-this.length+1).join(c||" ")};
// intersection
const intersect = xs => ys => {
const zs = createSet(ys);
return filter(x => zs.has(x)
? true
: false
) (xs);
You can’t perform that action at this time.
