Ted was right 5px was to small!
I increased the width to 100px and I can see the buttons all the same width now however, the buttons no longer work.
My origional html code is:
<input type="submit" value="Customer Info" onclick="changeViewCustInfo();">
This works, but the button widths fit the value text.
Using:
<input type="submit" value="Customer Info" style=" width:120px; height:500px onclick="changeViewCustInfo();">
My buttons are all 120px wide but the 'onclick' attribute no longer works.
I tried:
<input type="submit" value="Customer Info" onclick="changeViewCustInfo() style=" width:120px; height:500px;">
But this produced script errors.
any ideas?
