如何创建PHP内联悬停效果？

I'm having problems creating some hover effect.

I have `

<p class="proCalBand" style="border-left: 10px solid '.$row["act_format"].';"><a href="'.$page_url.'"><img src="'.$row["custom4"].'" class="slikca" /></a>

I want

style="border-left: 10px solid '.$row["act_format"].';"

to be 15px when hover over it how can I acomplish this? (maybe some slower transition would be great also ;) )

Is this even possible?

I tried onmouseover` but it's not working.

Any Ideas?

Thank you R

You should be able to use pure css to change just the border-width from 10px to 15px on :hover like this:

p.proCalBand {border-width:10px;}
p.proCalBand:hover {border-width:15px;}
