由 雨燕双飞 提交于 2019-12-14 04:00:25
问题 I want to generate a matrix of css selector in the form of .cX.rY selectors for a grid of something like 10 x 10. But I'm not seeing how I can do this less (I'm pretty new to .less). I'm using DotLess too, so perhaps there are some built-in limitations with that; I don't know for sure on that front. @col-width: -24px; @row-width: -24px; .img-pos(@col, @row) { background-position: (((@col - 1) * @col-width) - 1) (((@row - 1) * @row-width) - 1); } .c2.r1 { .img-pos(2, 1); } .c2.r2 { .img-pos(2,

由 假如想象 提交于 2019-12-13 06:28:05
问题 I'm trying to use use_percentages to generate an image sprite with background position by percentage. But after compiling the SCSS file, the background-position declaration is still in pixels.

jquery - click & activate active button

由 混江龙づ霸主 提交于 2019-12-13 05:16:07
问题 In jQuery: Scenario ** - I have four Divs that have hover effects. - All use a jquery animation to move the backgroundPosition to show the hover state.

I would also like the buttons to be aware if any other buttons have been clicked and remove the current click state and begin to animate the new click state on the new selected
