Proper div sizing without using pixel values - html

Question

My case is as follows. I have a div with two children divs. I'd like the 'event' div to be 300px of width and height. First requirement is to keep the size of the 'event' div when 'content' and 'bar' elements use 100% of parent's width. Secondly as for now, borders of 'content' element are not visible. Is it possible to fit everything inside without using hardcoded values and get this display properly in most of the modern browsers (FF, Chrome, Opera, IE7+) ?
This is what I'd like to achieve (notice the left red bar which takes 100% height and doesn't collide with the grey border around the event element):
And this is what I have. Html :
<div id="wrapper">
<div id="scheduler">
<div class="event" style="top: 30px; height: 300px; width: 300px">
<div class="bar"></div>
<div class="content">
<div class="inner-content">Some text</div>
</div>
</div>
</div>
</div>
, css :
#wrapper {
width: 600px;
height: 600px;
}
#scheduler {
background-color: #E1FFFE;
display: block;
height: 100%;
width: 100%;
padding: 0 10px;
position: relative;
}
#scheduler .event {
display: block;
float: left;
position: relative;
width:100%;
overflow:hidden;
}
#scheduler .event .bar {
background-color: red;
display: inline;
float: left;
height: 100%;
position: relative;
width: 5px;
}
#scheduler .event .content {
background-color: white;
border: 1px solid #CCCCCC;
border-left: none;
display: inline;
float: left;
height: 100%;
position: absolute;
width: 100%;
}

Answer 1

Try this. Take out the bar div, then change the .content css to:
#scheduler .event .content {
background-color: white;
border: 1px solid #CCCCCC;
border-left: 5px solid red; // replaces the bar
display: inline;
float: left;
height: 99%; // a bit of a hack to fit the border in
position: relative;
width: 98%; // hack
}

EDIT: Code with the .bar still in place:
#scheduler .event .bar {
background-color: red;
display: inline;
float: left;
height: 99.9%; /* Small offset at bottom */
position: relative;
width: 5px;
}
#scheduler .event .content {
background-color: white;
/* revised border */
border-top: 1px solid #CCCCCC;
border-right: 1px solid #CCCCCC;
border-bottom: 1px solid #CCCCCC;
display: inline;
float: left;
height: 99%;
position: absolute;
width: 98%;
}

I don't think I fully understand your quandary, however, with the only difference I can spy between your desired outcome and your current work being the presence of the borders -- switching overflow:hidden; on #scheduler .event to overflow:visible; produces something that visually looks to me like it achieves the desired affect.
