How to make div with position absolute does not go beyond the edges of the browser?

Better certainly a living example to look at. But in itself, the presence of right: 100% not necessary.
The easiest option: to reduce right or add left: 0 to the end.

so you asked him a huge right indent to 100%, and how he should not be circumcised?

Any way, a block with position: absolute does not include the edge browser, if only it is not relative to the html/body is positioned

The answer is simple - either don't do absolute positioning, or not move the unit outside the window
