Changing text size in the entire main menu section

I love the simplicity Sparkling offers. Thanks for such a good product.

This thread is about one issue I’m presently facing.

I want to change the size and font of the text in the main menu section. I Googled for possible solution and found only one code performs well on my website.

/change men font and size/ a {
font-family: arial;
font-size: 16px;

But the effort only changes the font size of the text in the dropdown section, which originates from the main menu. Pls refer the image. Meaning while I want to change the entire text size in the main menu, the code I pasted on additional CSS only changes the size of text from dropdown, and not the main menu.

I want a resolution that is effective for the entire menu section, main text and dropdown text included.

I know I will find an effective solution now. Hopeful! Thanks.
