What should be the appropriate size for repeated tiled css background images? _html/css_WEB-ITnose

Reply to the discussion (solution)

Is there any software or method specifically designed to test the effect of web pages?

Generally one pixel is enough.

Since it is 1 pixel, why not just use background-color?

Transparent, translucent cannot be set by color alone. Agreed that one pixel should be fine.

No, if it is too big, it will occupy bandwidth resources. 1px is enough.

1PX and 100PX are the same. The scientific approach is that 1PX loads more times but is faster, 100PX loads less times but loads larger images
