Create CSS file and link it in the head of your page.
Remove all inline styling of your table and add class="my-table" (name it whatever you like). If you know this particular style will be for this one, single table (as opposed to more then one table, add id="my-table" instead.
To your asp:Menu add CssClass my-menu
Your CSS:
.my-table,
#my-table
{
width: 100%;
height: 166px;
}
.col_w450
{
width: 79px; background-color: #99CCFF;
}
.my-menu {
width: 150px;
height:24px;
line-height: 2em;
background-color: #FFFBD6;
}
If you're doing web development, learn CSS. There is fairly basic tutorial at w3schools.com which should get you started.
If this helps, please accept the solution. Thank you and good luck.
