Adding active nav link decoration
I took some inspiration from Lukas's site and have added an active link decoration to the nav bar if the user is on one of those pages. It's a helpful visual to have IMO.
I had to tinker around with the styling for the blog link, since it's less straightforward than my other nav pagesβbut it seems to be working properly now.
I've also updated the CSS from my last design update post, since I've made a lot of random, marginal tweaks since then.
