If you charge for something online, having a dedicated page on your site where you explain what the charge is on a credit card statement is a good idea. You can point people to this page via a short URL right on the credit card statement.

Personal Blogs of Web People That I Like To Read

My favorite blogs are personal blogs of one person. I like it when blogs "have a voice" and personal blogs can't help but have that since all the writing is by the same person. I read a bunch of them and I thought I'd share. Below is a big ol' list that are specifically people that blog, generally, about web stuff - be it design, development, entrepreneurship, typography, business, illustration, whatever. You probably know a lot of them. Maybe some of them you don't.

Window Inactive Styling

Using some non-standard pseudo selectors, you can change the styling of things when the browser window is inactive. The only "practical" use right now is text selection colors, which automatically do this unless you override it. But we'll fix that!

Outer Border Radius Tabs

Imagine a real-life tabbed folder. The tabs on those aren't only rounded at the top of the tab, but they also connected to the folder with a rounded edge. Top corners, easy, just border-radius. Bottom corners, not so easy. …

Border Radius on Images

Restart CSS Animation

With CSS animations (ala @keyframes) it's not as easy as you might think to "restart" it.

Let's say you set it to run once:

.run-animation { -webkit-animation: my-fancy-animation 5s 1; -moz-animation: my-fancy-animation 5s 1; animation: my-fancy-animation 5s 1; }

Font Sizing with REM

One of the problems with using "em" as font sizes is that they cascade, so you are forever writing rules that select nested elements to reset them back to 1em; CSS3 now has rem ("root em") to prevent that issue. …

Tables of data can only squish horizontally so far, so they can be a pain to browse on small screens (like mobile devices) where you may need to scroll both horizontally and vertically to browse the information at readable text sizes. We'll explore a CSS-based possible-solution to this issue.

Value Bubbles for Range Inputs

HTML5 range inputs, in supported browsers and by design, don't show the user the actual value they are submitting. If you want to use the cool slider, but show the value, you'll have to do that yourself. Here we use the output element and jQuery to show the current value in a bubble that hovers above the range input.
