I also uploaded a reduced version of the logo (75 px tall). But original 100 px tall logo still appearing.

Code I changed in style.css. I input a WIDE variety of numbers. Yet top always measures 100:

/* begin —————————————- top */
#top {
position: relative;
width: 100%;
height: 130px;
background: #FFF; [background color did change to white]

/* begin —————————————- menu */
#mainmenu {
position: absolute;
z-index: 10;
top: 230px;
width: 100%;
