I've been writing HTML forever, but really never looked at the new HTML5 tags. For the most part, I'd devolved into using DIV and SPAN and FORM and a few other tags to code up webpages. That's OK for writing software, but it was getting pretty stupid when I was putting in code like DIV CLASS="address". A quick trip through the HTML5 tags revealed a cornucopia of tags relevant to writing academic papers and computer programming tutorials.
We all take it for granted that most sites will have a user registration system, and way to log in. We're used to it, and most people are unaware of how complex it is.
So, how complex is it?
It's around 15 different steps or screens.
I've done it a dozen times, and I think that's about right.
I'm one of those HTML losers who doesn't use the REL attribute unless is is LINK REL="stylesheet" HREF="...", or if it's provided in some template and I just paste it. (You can also use it for linking RSS and Atom feeds, but I rely on the software to do that for me.)
The core idea is, in addition to the data, you send over some information about the possible URLs you can use as a next step.
It's not hard, but there are a lot of little details to make it look reasonable and not completely goofy. I think it moves a little weird - and it should respond to both x and y axes, but doesn't.
This is a somewhat elaborate example of how to use conditional CSS and transitions to create a fluid, responsive stack of rectangles that are polite enough to stack up when the screen is narrow. The idea is I'm working on is to have a menuing system that stacks when the screen shrinks.
I don't know anything about CSS Transitions, so I made this little demo to try it out. It's ultra-simple, and I normally wouldn't post this kind of thing, but the examples I saw were a lot snazzier, so it was harder to read the code. (To this end, this is probably too fancy.)
Python and Django like snake_case.
AngularJS feels like Java, and likes camelCase.
HTML likes dashed-words.
MySQL docs like snake_case, but I see more PascalCase used in databases. It's case-sensitive, too.
Parse.com uses PascalCase for tables/classes, and camelCase for columns/properties/fields. That's like Java OOP.
Django likes to append _id to your primary keys.
So... the problems start to happen when one piece of named data is passed from one layer of the system to another. It's just a good policy to use the same names at all layers, if possible.
This is a common UI element that hovers between "pattern" and "anti-pattern", but it's one I've seen in Drupal, WordPress, and a few other places. It's the button next to a link, where the link acts just like a button:
Technically, it's a violation of UI principles, to have a link that does something to the server's state. Anthony at uxmovement thinks so, but I disagree with him, because the way the link is next to the button, it's obvious that it complements the button.
I have to learn the Chromium bug reporting system. Found an interesting rendering bug if, on a label, you specify a padding with an even number of points (pt), the rendering is shifted up a little bit, and the border can disappear if it's adjacent to another element.
Two examples are attached, differing only in the amount of padding.
Maybe it's a difference in how the values are calculated and either rounded off or truncated.
The problem goes away if you use pixels instead of points.

Here's a bit of the article:
Dang, but it took me forever to learn CSS. Maybe I should have used a book. Here, I'm going to share with you the hard-found knowledge, presented using technical programmer jargon. (Revised in 2014.)
What is Cascading Style Sheets (CSS)? The typical answer is that it's a way to separate the way a page looks from the the underlying HTML, which describes the structure of the document.
This snippet of code can be modified and used to change the stylesheet on your page. I set it up to work against a layout extracted from Salsa, but it should work on generic pages. It's good for demos, discussions about a layout, trying different colors, etc.
