Change Font Size and Make Bold in Menu

I am new to the theme and am trying to change the Primary menu font size and to make the font bold. I am using the following code in the Additional CSS section but it does not appear to change it:

/change men font and size/ a {
font-family: arial;
font-size: 44px;

I have searched the forum for a previous answer but cannot find one.


Hello there,

I hope you are doing well today.

You can use the following CSS code to change the menu font size and boldness by going to Appearance > Customize > Additional CSS and pasting it there.

/*Menu font edit*/ .main-navigation .menu li a { font-size: 13px; font-weight: bold; }

Best Regards,

Thank you, it worked perfectly. I tried to change the color using the same code but adding:

/Menu font edit/
.main-navigation .menu li a {
font-size: 15px;
font-family: arial;
font-weight: bold;
font-color: #ff0000;

The color code does not seem to work, what am I missing?


I figured out to use color: #fffff;

Thank you, you have been most helpful.
