Jumbotron row does not take full space on portfolio challenge

I´m completing the Portfolio challenge on this CodePen.

Just as the About and the Portfolio div, the contact div should stretch over the whole jumbotron size as it´s class is row.

However, it does not and I don´t understand why, because thee div structure is the same as in the about or the portfolio div.

I guess is because the class. Try to add a new class in css with width and then give it to your buttons.

You don’t want to build a whole page within a .jumbotron as it’s just a single component. Remove that div and keep your rows inside a .container
