        <h3 class="sports-history">Track & Field</h3>
        <p class="sports-history">
            Some sporting feats ridicule expectations, fewer violate logic but the rarest of all added a defying of gravity to a hat-trick of achievements. At 3.45pm on 18 October 1968 in Mexico City's Estadio Olmpico Universitario Bob Beamon accomplished all three.

        <p class="sports-history">
            With the game locked at 10 - 10 with thirty minutes on the clock, a Munster scrum just outside the Biarritz line enabled Peter Stringer to do the unexpected and break on the blindside for an unforgettable try. A moment of sheer brilliance by the Munster and Ireland scrumhalf. The try proved to be crucial as Munster won by 23 - 19 to lift the European Cup in Cardiff.

It looks like you have some malformed code in your post, review this guide to see how to add code properly on the forum:

It also helps to add a link to the project and step you are stuck on. You can use the “Help” button that appears after three incorrect attempts to create a post that automatically links to the step.

You have two ids with name heading. You cant have that, the ids need to be unique to each element you use them on. Only classes can have the same name. Also, please try to explain more what you are trying to do. Not sure from your initial post

The help button as mentioned is not going to help here since this doesnt seem to be a FCC challenge
