Change input style to greyed out for the read-only textbox field

Now, can I have some help reducing the Age input (434) to the width of its
label, and hopefully still having height and weight on the same line.
Also, can you give me code to change the input field's appearance to look
'greyed out' or some other appearance to differentiate it from an active
field requiring an input. I have set the field to read-only, but that
hasn't changed the field's appearance

I used the Form Designer to style specifically the Age field.

This is the CSS code result.

#input_434 {

    width : 35px;

    background : #e1c2c2;

}

You may adjust the width px and background color to your preference.

Let us know if you need further assistance.

 

Thank you!
