Center the top menu.

Been trying all the different ideas I can find by searching and none are working for me. Have a feeling I have conflicting codes going on here. I have tried:

“.primary-navigation {
float: none; /* change from float right */
text-align: center; /* addition to center text */
}”

and

“.header-main {
text-align: center;
}

.primary-navigation {
float: none;
}”

Neither work and don’t find any other recommendations.

Have Twenty Fourteen, Styles, 2014 Styles, Fourteen Extended, and Sequel Child activated.
