Problem with white text

It looks OK to me…

Oh,you mean on the home page…. sorry.

.home div.wpcf7 p {
    color: #000;
}

To add or override CSS: use the “Additional CSS” option in the customizer.? https://codex.www.ads-software.com/CSS#Custom_CSS_in_WordPress

Learn to use the Chrome Developer Tools or Firefox Developer Tools to help you see and test changes to your CSS.

If css you put in isnt overriding the original, make sure you put !important at the end of your css. eg
.home div.wpcf7 p {
color: #000 !important;
}
