Answer 1

I have it with the exception that when there is empty space my right div is eating it (with text right aligned). You don't list that as an ask, so I was unsure if it was just how you drew it? Fiddle here: http://jsfiddle.net/mdares/fSCr6/

HTML:

<div class="container">
    <div class="left">Some Text, Repeat, Repeat, Repeat, ,Some Text, and then: </div>
    <div class="right">other Text ttt other Text tttother Text tttother Text ttt</div>
</div>

<p />

<div class="container">
    <div class="left">Some Text, Repeat, Repeat, Repeat, ,Some Text, Some Text, Repeat, Repeat, Repeat, ,Some Text,</div>
    <div class="right">other Text ttt other Text tttother Text tttother Text ttt</div>
</div>

<p />

<div class="container">
    <div class="left">Some Text, Repeat, Repeat, Repeat, ,Some Text, </div>
    <div class="right">other Text ttt</div>
</div>

CSS:

.container {
    width: 600px;
}
.left {
    max-width: 100%;
    background:red;
    white-space:nowrap;
    overflow:hidden;
    text-overflow:ellipsis;
    -ms-text-overflow:ellipsis;
    float: left;
}
.right {
    background:yellow;
    white-space:nowrap;
    overflow:hidden;
    text-overflow:ellipsis;
    -ms-text-overflow:ellipsis;
    text-align: right;
}

Except the container width That can be defined in % here's a solution. The only crack that worked was putting container backgroud as that of child one.

or else the last condition is really hard to achieve :) Just being True.

Here's the fiddle link

Here's the css

.container {
width: 100%;
overflow:hidden;
whitespace:nowrap;
max-width:100%;
    background-color:red;
}
.left {
    width:auto;
    background:red;
    white-space:nowrap;
    overflow:hidden;
    text-overflow:ellipsis;
    -ms-text-overflow:ellipsis;
    float: left;
    position:absolute;
    max-width:inherit;
}
.right {
    background:yellow;
    white-space:nowrap;
    overflow:hidden;
    text-overflow:ellipsis;
    -ms-text-overflow:ellipsis;
    text-align: right;
    width:auto;
    float:right;
}

See to it if it fits . Last condition really tough if some one has another solution to the last image you pasted then please share :)
