Outlining buttons

Hello fellow wordpressers,

I’m currently making a website using the Mesmerize theme and
absolutely loving it!

However, I’m currently stuck at the #features option. I’m trying to outline the orange buttons so that they are like right next to each other instead of all having different hights.

Can anyone help me out with this?

Sorry for being a WordPress noob, I’m still learning! ??
