			<fieldset>
				<legend><span class="field-name">Please select all that apply:</span></legend>
				<div class="checkbox">
					<label for="problem1"><input name="problem1" id="problem1" type="checkbox" value="Yes">A link, button or video is not working</label>
				</div>
				<div class="checkbox">

				</div>
				<div class="checkbox">
					<label for="problem3"><input name="problem3" id="problem3" type="checkbox" value="Yes">Information is missing</label>
				</div>
				<div class="checkbox">

				</div>
				<div class="checkbox">
					<label for="problem5"><input name="problem5" id="problem5" type="checkbox" value="Yes">Login error when trying to access an account (e.g. My Service Canada Account)</label>
				</div>
				<div class="checkbox">
					<label for="problem11"><input name="problem11" id="problem11" type="checkbox" value="Yes">I can't find what I'm looking for</label>
				</div>
				<div class="checkbox">

				</div>
			</fieldset>

Conversion from a deprecated code

Expected result

When the form is submitted, it need to be hidden and a "Thank you" message is shown on success or on fail. The CSS class started with gc-rprt-prblm must not be re-used ouside the report a problem context because it might apply undesirable style.
