How does absolute positioning work?

Question

css

Good afternoon, is it correct in this case (on the screen) to use positioning - put the send icon on the input https://hsto.org/webt/60/91/dc/6091dcd571c87164940... .
If not, how is it right?
if so, how to adapt correctly so that it does not peel off?

Answer 1

Answer 2

in batch with relative. Relative is relative to what to nail, and absolute is what to nail. It seems to hang in the air, and does not occupy the usual space. If reading is difficult = a good lesson from Dmitry Lavrik.
