Remove Page Title and Attributes

Your Homepage doesn’t seem to have any issues. Now for the other pages you should add a CSS rule to the Custom CSS section of the wp theme customizer.
I’m guessing by “attributes” you meat that breadcrumb line below the page title that has “>”s in it, if that’s correct the rule is:

.entry-header { display: none; }

Hope that helps.

Thank you. Can you also help me with moving my navigation menu down?

I used this CSS:
main-navigation li a {
padding-bottom: 0;
}

However, the drop-down menu moves with it and it no longer touches the header. How do I keep the drop-down menu where it is?

You Changed the theme and didn’t have the chance to test it. Send when ready.

Take a look now, please.

Add the rule:
.submenu { position: fixed; top: 173px; }
You may need to use !important if not applied
.submenu { position: fixed!important; top: 173px!important; }

Try it and let me see it.

Done. Did not change.

I cannot find the rule anywhere.
It didn’t applied for some reason…

Maybe delete the previous one and add this:

.main-navigation ul ul {
    top: 99px;
}

you may need to use:

.main-navigation ul ul {
    top: 99px!important;
}

Now it moved my navigation menu Up and the drop down menu right below it. What I’m trying to accomplish is to lover my main menu down and have the drop down menu open right on the header bottom line.

Your rule is missing:

.main-navigation li a {
    padding-bottom: 0;
}

Don’t erase that one.
Just add a line below the new one:

.main-navigation ul ul {
    top: 99px;
}

I did, but now I can’t click on anything on the drop-down menu. It disappears as soon as I try to select anything.

it’s because of the padding.
There’s a gap between the li and the submenu ul…
That padding was used for mouse hovering from one to the other.

Try using some padding and move the li up a bit (so the gap closes):

.main-navigation li a {
    padding-bottom: 20px;
    position: relative;
    top: 20px;
}

You get the idea. Trial and error the positioning.

It worked if I play with the numbers but that just moves the navigation up again.
