Question

What is the best way to assign a class to a read-only field in HTML and CSS?

My situation is as follows: I have jQuery code that uses an if-statement to add a specific class to an element based on the selected value on a form page. I also created another form where users can view the details of a previously filled out form. However, when the details page is displayed, the gray "read-only" background overrides the background color from the original class. I don't want to delve into the bootstrap files to modify the read-only background color code if possible. How can I apply the complete class (including the background color) to a read-only element?

Code snippet from the "Create" page:

<div class="col-md-12">
                <div class="col-md-10">
                    @Html.LabelFor(model => model.Question1, htmlAttributes: new { @class = "control-label" })
                </div>
                <div class="col-md-2">
                    @Html.DropDownListFor(model => model.Question1, new[] { new SelectListItem() { Text = "Pass", Value = "Pass" }, new SelectListItem() { Text = "Fail", Value = "Fail" }, new SelectListItem() { Text = "NA", Value = "NA" } }, "Select an option", htmlAttributes: new { @class = "form-control text-box centerline", @onchange = "updateEscalationsListeningScore()", id = "question1Answer" })
                    @Html.ValidationMessageFor(model => model.Question1, "", new { @class = "text-danger" })
                </div>
            </div>

jQuery from the "Create" page:

if (Q1Answer === "Pass") {
        $('#question1Answer').addClass("correctListeningAnswer").removeClass("incorrectListeningAnswer").removeClass("naListeningAnswer");
        Q1Score = 3;
        Q1PotentialPoints = 3;
    }
    else if (Q1Answer === "Fail") {
        $('#question1Answer').addClass("incorrectListeningAnswer").removeClass("correctListeningAnswer").removeClass("naListeningAnswer");
        Q1Score = 0;
        Q1PotentialPoints = 3;
    }
    else if (Q1Answer === "NA") {
        $('#question1Answer').addClass("naListeningAnswer").removeClass("incorrectListeningAnswer").removeClass("correctListeningAnswer");
        Q1Score = 0;
        Q1PotentialPoints = 0;
    }
    else {
        $('#question1Answer').removeClass("correctListeningAnswer").removeClass("incorrectListeningAnswer").removeClass("naListeningAnswer");
        Q1Score = 3;
        Q1PotentialPoints = 3;
    }

Code snippet from the "Details" page:

<div class="col-md-12">
                <div class="col-md-10">
                    @Html.LabelFor(model => model.Question1, htmlAttributes: new { @class = "control-label" })
                </div>
                <div class="col-md-2">
                    @Html.EditorFor(model => model.Question1, new { htmlAttributes = new { @class = "form-control text-box centerline", id = "question1Answer", @readonly = "readonly" } })
                    @Html.ValidationMessageFor(model => model.Question1, "", new { @class = "text-danger" })
                </div>
            </div>

        if (Q1Answer === "Pass") {
        $('#question1Answer').addClass("correctListeningAnswer").removeClass("incorrectListeningAnswer").removeClass("naListeningAnswer");

    }
    else if (Q1Answer === "Fail") {
        $('#question1Answer').addClass("incorrectListeningAnswer").removeClass("correctListeningAnswer").removeClass("naListeningAnswer");
        Q1Score = 0;
        Q1PotentialPoints = 3;
    }
    else if (Q1Answer === "NA") {
        $('#question1Answer').addClass("naListeningAnswer").removeClass("incorrectListeningAnswer").removeClass("correctListeningAnswer");

        Q1Score = 3;
        Q1PotentialPoints = 3;
    }

CSS

.correctListeningAnswer {
background-color: #c6efce;
color: #006100;}

.incorrectListeningAnswer {
background-color: #ffc7ce;
color: #9c0006;}

.naListeningAnswer {
background-color: #ffeb9c;
color: #9c5700;}

Instead of setting the field to readonly, consider using disabled instead. This way, your background will display correctly.

For instance, you can do the following:

input {
  background-color:#ffc;
}

<input type="text" disabled>

Alternatively, you could avoid using a form field altogether to present information. Extract the data from the initial form and display it using more appropriate elements such as span, which are not editable by default.

document.querySelector("button").addEventListener("click", function(){
  document.getElementById("dataOut").textContent = document.getElementById("dataIn").value;
});

<input id="dataIn">
<button type="button">Simulate a submit</button>
<span id="dataOut"></span>

If necessary, you can make your class selector more specific than the Bootstrap selectors to ensure that your styles take precedence over them.
