Hope it's the right place to ask help. I really need some guidance if possible.
So I'm a super newbie in Wordpress ( I don't know how to code and develop) and this is my first time to have a real formal official website.
And I bought a WordPress theme a few months ago. Until recent days, I just finished the basic layout style look( the most easiest way just rearrange the layout you know) based n the theme templates in Wordpress editor ( my host is Bluehost). But during the phase, I have some really hard problems especially for me as a non-technical guy, so may I ask:
How do I make the navigation menu font larger? And become normal type to display but not capital letters(please see the image a: https://www.pinterest.com/pin/318629742389963348 )?
My current WordPress preview URL is (not yet released） WordPress internal link, like this "http://box111111 (numbers).temp.domains/...", how do I change this to my official URL(www.xxx.com)? (Previously changed once but caused the preview pages can't open)
the sign up newsletter didn’t show, it said: “[contact-form-7 404 “Not Found”]” , not the normal look as the demo display, may I ask why this could happen? How can I adjust this? My newsletter service provider is MailChimp.
Thank you so much, I really appreciate. Merry X' mas and Happy New Year! ;->
