Is there a form element meant to provide instruction?


I know how to add labels to form inputs to 'label' what they are. I am wondering if there is something similar for describing what a field is in more details? I want to there to be little text under a text field but don't know if there is a specific element I should use... thanks!


There are many form specific elements that can be used to describe what's going on. As you've already mentioned, each input requires that it has a corresponding label. If you would like to further organize and give meaning to your form, you can use the 'fieldset' element to group related inputs.   Within each fieldset, you can create a 'legend' that describes the inputs. For instance, let's say we have a form that asks a user for their personal information, and details about an order. The source code could look something like this.
    <legend>Enter Your Information</legend>
    <label for="first">First Name</label>
    <input type="text" name="first">
    <!-- etc -->
    <legend>Order Details</legend>
    <label for="size">Size</label>
    <select name="size">
      <!-- sizes -->
    <!-- etc. -->
