Answer 1

You could use a container div:

    

        
some text here
    

Then use that to handle the float, and make its child position: fixed

.outer {
    width:50%;
    height:600px;
    background-color:red;
    margin:0 auto;
    position: relative;
}
.floatcontainer {
    float: right;
}
.inner {
    border:1px solid white;
    position:fixed;
}
.floatcontainer, .inner{
    width: 50px;
}
