I have the following code. Functionally, it's working great, but when you toggle between button 1 and button 2 and the div slides into position, the size of the div collapses. I'd like to make it so that the page doesn't resize when toggling back and forth. I'm figuring this is an easy fix, but I can't seem to get it right. Code is below. Any help is much appreciated. Thank you in advance!

Code:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

<script>
$(function () {
    $("[name=toggler]").click(function () {
        $('.toHide').hide();
        $("#blk-" + $(this).val()).show('slide');
    });
});
</script>
HTML Code:
<label>
    <input id="rdb1" type="button" name="toggler" value="1" />
</label>
<label>
    <input id="rdb2" type="button" name="toggler" value="2" />
</label>


<div id="blk-0" class="toHide">
<div class="center-form-img" >
<img src="{{media url="wysiwyg/form-inactive.jpg"}}" alt="" />
</div>
</div>
<div id="blk-1" class="toHide" style="display:none"> {{block type=core/template name=ContactUs template=cmg/ContactUs1.phtml}}</div>
<div id="blk-2" class="toHide" style="display:none">{{block type=core/template name=ContactUs template=cmg/ContactUs2.phtml}}</div>
