CHANGE HEIGHT AND COLOUR OF THE MAINMENU

how can I change the settings of the megamenu? I am looking at reducing the height of the menu and could not find the settings. Can you provide the instructions and the CSS?
I noted that all the fonts in my forms are in white. How do I change the colour of the font so that the input is visible?
2. All field labels in my forms are not showing either? Where do I activate the labels?
When i create forms, i cannot see my field labels beside the input box/selection box in my form. Can you advise?
