center

问题 I want a webpage, with the content centered, and specify a minimum width so it resizes on small screens of smartphones, but still looks fine on PCs. If I set the width of my div to 1024px, and margins auto, then the div stays centered when the browser window is stretched wider than that.

Usually I'd use css with top and left positions set to 50% with a negative margin equal to half the width and height, but obviously that wouldn't accomodate this need.

问题 I have a Google Map that works fine but I just need to tweak it so that when a marker is clicked and opens up a info window, I'd like that marker (and the map) to center on the screen. This is so that the info window is the direct focus. If it helps, I'm using Infobox.js to create the infowindows.
