CSS background-size cover and background-position

Question

HTML:

 #backgroundproduct { position: fixed; top: 5%; left: 5%; width: 90%; height: 90%; z-index: 12; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover; background-position: top; } 

 <div id="backgroundproduct" style="background-image: url(http://example.com/example.jpg)"> 

I'm using a images as a background image, only the lower part of the image is more important than the top.

How can I make the background go up a little?

Answer 1

If the bottom is more important: background-position: bottom;

background-position also allows percentage values: 0% 0%; by default.

The first value is the horizontal position and the second value is the vertical. The top left corner is 0% 0%. The right bottom corner is 100% 100%. If you only specify one value, the other value will be 50%.

You should try background-position: 0% -10%;

Answer 2

您可以使用：

background-position: center bottom;

Answer 3

Just to be clear, background-position percentages are calculated against BOTH the image and the background container. So, background-position: 25% 25%; would find the 25% point for both X and Y on the background container and align the image's 25%,25% point on top of that point.
