CSS Notes

You need to make a separate instance for the Harmony construct that houses the Logo and the Menu. Assign user classes to those columns. The class names I used were menu and logo. Set padding to zero.

.hmy-content-wrapper.menu .hmy-content,
.hmy-content-wrapper.logo .hmy-content {
padding: 0px;
}

Now write a rule to set the entire first Harmony instance to position sticky, as follows:

#p7HMY_1 {
position: sticky;
top: 0px;
}

Reset Media Queries in Harmony and MXM style sheets to use a breakpoint of 960px. In the Harmony CSS file locate the query:

@media only screen and (min-width: 0px) and (max-width: 600px) {

Change it to this:

@media only screen and (min-width: 0px) and (max-width: 960px) {

Now locate the responsive media query in the MXM style sheet (do not alter the one that has a 5000px breakpoint)

@media only screen and (min-width: 0px) and (max-width: 768px) {

Change it to this:

@media only screen and (min-width: 0px) and (max-width: 960px) {

That's it. Your menu is really packed, hence the need to adjust breakpoints.
