Background-attachment fixed issue #44

Open WPThemer opened 7 years ago

WPThemer commented 7 years ago

Hi, this is so awesome, and I want to use it in any case, I already spent 4 hours without fixing it.. if I set background-attachment: fixed; the image flickers a lot, it only seems to work in Chrome.. I tried to remove the property position:relative; and set it to position:static; then the mouse over effect doesn't seem to work. Is there any workaround for this ?

thanks

I'm unfamiliar with the flickering, and I cannot think of what's causing it... Could you create a minimal test case to demonstrate the issue?

Have experienced the same - see here: http://nonchalant-mailbox.surge.sh/

The image jumps / flickers as you scroll down in most browsers for me.

The only "workaround" (if you can even call it) that I can think of at the moment is to not use background-attachment: fixed. If I'm not mistaken, nowadays browsers do some trickery to make scrolling perform better/more smoothly, but it can cause javascript logic which depends on the viewport position to lag behind, which causes the jumpy behavior.

Hey! Even worse, with collapsing divs (e.g. in Bootstrap 4), the whole background collapses, too. Is there a workaround? Even when not using background-attachment:fixed, the image while horizontally resize as soon as a div collapses/shows. Vertically though, it will just scroll through the background color.

I hope I was able to express the issue clearly^^ love your ripples!

@i3reakf4st Could you demonstrate it somewhere (jsfiddle or codepen or whatever)? I don't have a good picture of what's happening in your case.
