Mysterious horizontal lines on my site when rendered on iPad

Question

The following site:

http://staging.jungledragon.com

Has a few rendering issues on the iPad using Safari, so I'm trying to fix them. There is one issue where I am stuck though. If you have an iPad, open the site in portrait mode. There are two unwanted horizontal lines appearing, a top one that crosses the tabs (Popular, Fresh, etc) and a bottom one that sits right above the lizard illustration. Both lines should not be there.

These lines do not appear on any other browser tested, including Safari on Windows. When you move that same site into landscape mode on the iPad, the top horizontal line dissapears, whilst the bottom one stays. If you zoom in a bit to the bottom line, it then dissapears too.

I've been trying out various CSS fixes to no avail and am now beginning to think this is a rendering issue of Safari, although possibly triggered by me.

Any help is greatly appreciated. It seems like a minor issue but I hate sloppiness.

Answer 1

The issue's have to do with the way Mobile Safari handles background images. The green line that pops up (just inside your content area) is from another element.

Try 'over sizing' your images. For instance: A image gets cut off at 100 pixel height, make that image 110 pixels high. This works for me... most of the time.

Edit: I did check the site on my iPad and I just saw that single line popping up. Also note that it disappears when you zoom in/out which tells me it's a rendering bug (not something in your css).

Oops - how did that happen?

The meta to go in the head tag to to stop zooming on the iPad:

<meta name="viewport" content="initial-scale=1, maximum-scale=1">

Answer 3

An alternative is to specify the size of the background. This can be done with the css selector "background-size".

If your background image is 40 pixels high, the following code will prevent horizontal lines from showing up on the iPad: { background-size: 100% 40px }
