Iphone/Ipad crashes when zooming

Question

Go to this page with an Iphone (safari): https://www.blush.no/k/kc.aspx?bn=15411 and then try to zoom all the way in to one of the buttons that says "Kjøp". If it does not crash the first time, try to zoom out and then in again. You will experence either:

1. The iphone is actually restarting
2. The page is reloaded with a message "A problem occured with this webpage so it was reloaded"

From my experience this is easiest reproduceable with Iphone 6+.

Something in the CSS triggers this, but i have no idea what. If I remove all the CSS, the page does not crash, and also if I remove all CSS except bootstrap, it's working OK.

If i start to remove parts of the CSS, its getting better and crashes not so often, but I'm struggelig to pinpoint what exactly is going on.

Edit: Crash report:

Does anyone have any clue of what might be wrong?

Answer 1

We were doing a lot of debugging, and we finally found a solution. We have a "skip navigation" link which is only showing when you press "tab" on your keyboard. This was initially set to "text-indent: -10000px". This probably causes the viewport to be over 10000 px in width and then causes the phone to use too much memory and then eventually crashes. We have fixed this by removing this css rule, so blush.no does not crash that much anymore.

Iphone still have a problem with memory leakage, and until they fix this, the site will sometimes crash, but not as near as much as it did before.
