Frontend Friday: Got questions?

For this week, I’m doing a free-for-all: if you have something you’re curious about in terms of HTML, CSS and JavaScript, post your question in the comments and I’ll cover your question in future Frontend Fridays. Nothing is “too simple”, so feel free to post questions (please try to keep clear of Enthusiast-only questions though! ;) ).

The reason for this (rather abrupt) post is that due to my rather freaky schedule this week (I’m moving by end of the month, and we’re hopefully signing a tenancy agreement this coming Monday, finally), I wasn’t able to prepare for this week’s Frontend Friday. I had a draft in the works but unfortunately, it needs more research than I have time for this week.

Let me know in the comments! :)
