Can't center/make text on top menu bigger

Hello,

I cannot make the text in the top menu bigger, and when someone scrolls down and the menu’s color appears they don’t look centered. I’d like them to look centered and to make the text bigger. Is there any way to do this?

I’m attaching two images

Hi,

Did you set the top menu to sticky? if so, you can align the top menu to the middle by adjusting the value of margin-top from css code below:

.site-header.fixed.float-header #mainnav ul li {
    margin-top: 10px;
}

you can put the code using simple custom css plugin.`
