I want these radio inputs to stretch across the screen, rather than one beneath the other:
HTML
In your case, you just need to remove the line breaks (<br> tags) between the elements - input elements are inline-block by default (in Chrome at least). (updated example).
<input type="radio" name="editList" value="always">Always
<input type="radio" name="editList" value="never">Never
<input type="radio" name="editList" value="costChange">Cost Change
I'd suggest using <label> elements, though. In doing so, clicking on the label will check the element too. Either associate the <label>'s for attribute with the <input>'s id: (example)
<input type="radio" name="editList" id="always" value="always"/>
<label for="always">Always</label>
<input type="radio" name="editList" id="never" value="never"/>
<label for="never">Never</label>
<input type="radio" name="editList" id="change" value="costChange"/>
<label for="change">Cost Change</label>
..or wrap the <label> elements around the <input> elements directly: (example)
<label>
<input type="radio" name="editList" value="always"/>Always
</label>
<label>
<input type="radio" name="editList" value="never"/>Never
</label>
<label>
<input type="radio" name="editList" value="costChange"/>Cost Change
</label>
You can also get fancy and use the :checked pseudo class.
Here is updated Fiddle
Simply remove </br> between input radio's
<div class="clearBoth"></div>
<input type="radio" name="editList" value="always">Always
<input type="radio" name="editList" value="never">Never
<input type="radio" name="editList" value="costChange">Cost Change
<div class="clearBoth"></div>
This also works like a charm
<form>
<label class="radio-inline">
<input type="radio" name="optradio" checked>Option 1
</label>
<label class="radio-inline">
<input type="radio" name="optradio">Option 2
</label>
<label class="radio-inline">
<input type="radio" name="optradio">Option 3
</label>
</form>
To get your radio button to list horizontally , just add
RepeatDirection="Horizontal"
to your .aspx file where the asp:radiobuttonlist is being declared.
