adjust the height

Hey schweg33,
The height of the text block is based on the content inside of it. The paragraph tag in it will has top & bottom margin, and the section that it is in has padding from your custom css:

.template-page.content.av-content-full.alpha.units {
    padding-top: 20px !important;
    padding-bottom: 20px !important;
} 

It would probably look nicer if you removed the background color.

Best regards,
Mike

Hi,
The top padding is set by your custom css:

.template-page.content.av-content-full.alpha.units {
    padding-top: 20px !important;
    padding-bottom: 20px !important;
} 

Change 20px to zero if you want to remove it, but note this will affect all of your pages.
While you have set the text color to white, your text is bold (strong) which has a blue color, either remove the strong tag, or add the color to the span style, like your font size.
If you don’t know how to do that try this css:

.avia_textblock p span[style*="color: #ffffff"] strong span[style*="font-size: 14pt"] {
    color: #ffffff;
} 

Best regards,
Mike
