how can I move any image on web page with the pixels?

Answer 1

you can't move image with pixels....pixels are used to describe the size of image....you can use alignment for this purpose e.g align="centre" or bottom,right,left etc.

Answer 2

Theirs quite a few ways a couple simple css ones would be:

img {
position:absolute;
top: 250px;
left: 400px;
}

img {
margin-left: 50px;
margin-top:300px;
margin-bottom:;
margin-right:;
}

theirs other ways but each way has its own proper use depending on the situation
