From: Tom Date: Mon, 17 Nov 2014 15:31:46 +0000 (+0100) Subject: IE < 10 does not support gradients. X-Git-Tag: v1.7.0~1^2~105^2 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=refs%2Fpull%2F230%2Fhead;p=gitblit.git IE < 10 does not support gradients. Since the new imgdiff UI heavily used gradients, this leaves IE9 and IE8 users with a complete disfunctional UI. Replaced all gradients by simpler means: * Vertical handle: instead of 2px wide gradient, use a 1px background and a white border-right * Opacity slider: No gradient but a simple border and background-color * All radial-gradients replaced by small pre-computed PNGs * Checkerboard background done with a small repeated PNG With these changes, the imgdiff UI is fully functional even in IE 8. Visual changes in other browsers are barely discernible. --- diff --git a/src/main/resources/gitblit.css b/src/main/resources/gitblit.css index 5a62de0b..e0570ceb 100644 --- a/src/main/resources/gitblit.css +++ b/src/main/resources/gitblit.css @@ -1440,6 +1440,8 @@ div.diff > table { /* Image diffs. */ +/* Note: can't use gradients; IE < 10 doesn't support them.
