Ans : The default rendering of CSS in various browsers is different, "reset" CSS resets the default style of the browser by redefining the label style, and the style remains consistent.
Ans : CSS Sprites page is to integrate some small pictures to an image file, and then use the CSS background-image, background- repeat, background-positiona combination of background location, background-positionyou can use numbers can accurately locate the position of the background image. Can reduce http requests.
Ans : <link rel="stylesheet" type="text/css" media="screen" href="xxx.css" />
The attribute specified by media is the device, the display is screen, the printer is print, the TV is tv, and the projector is projection.
But the print style sheet should also have some precautions:
1 It is best not to use background images in the print style sheet, because the printer cannot print the background in CSS. If you want to display a picture, please use html to insert it into the page. 2 It is best not to use pixels as the unit, because the print style sheet will be the real thing, so it is recommended to use pt and cm. 3 Hide unnecessary content. ( @print div{display:none;}) 4 It is best to use floating attributes sparingly in the print style sheet, because they will disappear. If you want to know the effect of the print style sheet, just select the print preview directly on the browser.
