Below is the visual framework for a practice slide show I am tutoring my self with. In webkit browsers and Firefox I get the controls to line up correctly, but on IE8 the far right control drops out and goes lower than I would expect.
I have attached the code and some images in hopes that some one can suggest what I am doing incorrectly.
Thanks!

when you order with float they all must be floatet :)
I advice you after those floats to put one clear div CSS pref

.clear {clear:both}

Placing the margin 0 and padding 0 in each of the DIVs worked. I don't understand how and where to apply your suggestion of the ".clear {boath}".

<div id="slideShowBoxControlls">
                <div id="arrowLeft"></div>
                <div id="descriptionBox"> </div>
                <div id="arrowRight"></div>
            </div>
<div class="clear"></div>
