How can I change text in input field?

I have tried to change the text color in the input field, but it is still white and you can barely see what you are typing in the form. I have tried the suggestion of highlighting the field and changing text color. The text color is on black, but it is still showing up white when I try to input text in the input field. I have attached a screenshot of how light the text is in the first couple text boxes. I have also attached a photo to show how my form is set to black on the font. What am I doing wrong? I just need the input field to be a dark colored font.

Thanks!

    color: white;

    font-weight: bold;

}

Result:

You can change the color property if you want to: https://www.w3schools.com/colors/colors_picker.asp
