Show/Hide function -extra white space

In relation to my other post earlier- Show/hide section based on dropdown -js that got answered by @Moob I now have another issue. With the same code- whenever the page is reloaded, there is a huge gap after the drop-down where the text will display if a certain choice is selected. Any ideas why it is doing that?

Here is the codepen.io: http://codepen.io/Nestalna/details/qpjsy

<script type="text/javascript" src="http://code.jquery.com/jquery.js"></script>
<script type="text/javascript">
    function show(aval) {    
        if (aval == "0") {//if 1 then show it
            optionyes.style.visibility='visible';
            optionyes.style.display='block';
            Form.fileURL.focus();
    } 
        else {//for everything else hide it
            optionyes.style.visibility='hidden';
            optionyes.style.display='none';
    }    
}
</script>

<div class="row">
            <label id="title" for="degree">Which degree are you interested in? </label><br />

                <select id="degree" name="degree" onchange="java_script_:show(this.options[this.selectedIndex].value)" >
                    <option selected="selected" value="Please select one"> Please select one </option>
                    <option value="0" > Concurrent Enrolment </option>
                    <option value="1" > 2015 Applied Bioethics Summer Study </option>
                    <option value="2"> Non Degree (9 hours or less) </option>
                </select>
        </div>      

        <div id="optionyes" style="visibility:hidden" >You have selected <strong>red option</strong> so i am here Lorem ipsum dolor sit amet, mel fugit epicuri laboramus ei, modo elit elitr sea te.

That gap is there, because visibility: hidden; unlike display: none; will keep the occupied space and not free it up. In the perspective of the layout engine, visibility: hidden; does not mean anything, only the rendering engine will not render that part.

Change the <div id="optionyes" style="visibility:hidden" > to <div id="optionyes" style="display:none" >

Because you set the visibility to hidden, and that doesn't remove the element, it just doesn't display it while still occupying the original amount of space. 

<div id="optionyes" style="visibility:hidden">

Use display:none if you want it to act like it doesn't exist in the page.
