Hi! @paulproteus

I would be happy to work on all of the tasks that you mentioned, but I have to go back to Toronto on 17th April, Thursday and I will only be getting a chance to work on these once I am in Toronto.

From now on, I'll try to analyze the problem that I'm working on and see if it can be or if it is necessary to break it down into separate issues based on the type of problems.

I'll be adding the comment in base.css about the clear: both;, but one question, should I file a separate issue about the comment or should I just make a commit?

And, yes, I think we should add some explanations to the Front-end style guide about the clear: both; issue and about how to phrase things well in the missions. I think that it would act as a good reminder in the future when we have to tackle problems similar to these. So, I will write some guidelines in the Front-end style guide right away.

Hope you had a safe and enjoyable journey!

Thanks
