how to move your logo up or down

does anyone know how to move your logo up or down on the page?

Yes, you need to adjust your stylesheet to position the logo element differently.
If you use the DefaultClean theme, your stylesheet is here:
/Themes/DefaultClean/Content/css/styles.css

Open it with notepad and Ctrl+F search on this:
.header-logo

You should see this:

.header-logo {
  margin: 0 0 20px;
  text-align: center;
}

Then you just need to use absolute positioning to place the logo wherever you want it to appear:

.header-logo {
    position: absolute;
    left: 100px;
    top: 150px;  
    margin: 0 0 20px;
  text-align: center;
}

Or maybe just need to add a little padding to the top of the logo:

.header-logo {
  margin: 0 0 20px;
  text-align: center;
  padding-top: 50px;
}
