Handling Page Transitions on Single Page Web Apps

zoom

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.

Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

Purchase the cert

You can’t perform that action at this time.
