You can use Css3 attribute selector or attribute value selector.
/This will make all input whose value is defined to red/
input[value]{
color:red;
}
/This will make conditional selection depending on input value/
input[value="United States"]{
color:red;
}
There are other attribute selector like attribute contains value selector,
input[value="United S"]{
color: red;
}
This will still make any input with United state as red text.
Than we attribute value starts with selector
input[value^='united']{
color: red;
}
Any input text starts with 'united' will have font color red
And the last one is attribute value ends with selector
input[value$='States']{
color:red;
}
Any input value ends with 'States' will have font color red
