I made a hovering html code table , but it's only works when i first hovered it ! I want it to works straight away after i open my blog page ! Can anyone help me with the code ?

This is my code for the hovering effect :

onmouseover="this.style.opacity=1;this.filters.alpha.opacity=100"onmouseout="this.style.opacity=0.1;this.filters.alpha.opacity=40"

Thx!
