              <!-- :read-only -->
<section class="example-cntr read-only">
    <h1>CSS <code>:read-only</code> pseudo-class</h1>
    <p>The <code>:read-only</code> pseudo-class targets an element that cannot be editable by the user. This pseudo-class is very similar to the <code>:disabled</code> pseudo-class, it all depends on which attribute is used in the markup that would tell
        us which pseudo-class to use.</p>
    <p>This is useful for example in situations where we need to show prepopulated information on a form that cannot be altered but that still needs to be displayed in form elements for submission purposes.</p>
    <p>In the following example, this input has the <code>readonly</code> HTML attribute, so it will have gray text, and thus we can target it with the <code>:read-only</code> pseudo-class.</p>
        <span>Are you read-only?</span>
        <input type="text" value="Yep! I am read only" readonly>
