问题 I have a script that loads in a div with images running jQuery Cycle Lite Plugin. I got the tip that I could us the "after" function in that plugin to make changes to the picture each time the image is refreshed. So I wrote this: $("#display div").css({ margin: "0 auto", "text-align": "center", }); The html built like this: <div id="display"> <div id="slideshow1"> <img ... /> </div> </div> This isn't working, whats wrong? ( this is supposed to center it horizontally, i need to center it

由 我与影子孤独终老i 提交于 2019-12-23 08:34:07
问题 Hey i'm trying to integrate SFML and Box2D, and SFML has made setting centers for sprites, shapes, etc. very easy.
