If CSS properties attended high school, you would never expect to see the border property sitting at the cool kids’ table. Sure, it’s a useful property and all — as long as you’re looking accentuate the boxiness of a design, right?
Actually, you’d be surprised at just how cool the border property can be. Please take the following dozen exhibits as proof that the CSS border property is a lot cooler than we give it credit for. Read On…
The realm of CSS is a realm of boxes. Everything on the page is a box, within a box, within a box. No wonder it’s so common for beginning CSS developers (or, in my case, poor graphic designers with too much CSS experience) to create boxy layouts!
However, the forthcoming CSS3 specification offers us a glimmer of hope in the form of rounded corners. That’s right — once CSS3 is commonly supported, we’ll be able to childproof all those pointy edges and beautify the web in the process.
And better yet, a few browsers already support rounded corners! As I’m writing this, you’re pretty much limited to Mozilla/Firefox and Safari 3. However, this list is bound to grow as time goes on, so it couldn’t hurt to start playing around with this feature. Especially considering that, in the browsers that don’t support rounded corners, nothing bad happens — the user just sees regular, square corners.
For now, to get the code to work, you’re stuck using proprietary CSS tags: they won’t validate, but they’ll just be ignored by browsers that don’t support them. The code itself is pretty simple; for example, to create a div with nice rounded corners with a radius of 5 pixels, you’d just write something like this:
And this rule will create a div that looks like this:
The two properties of note here are “-moz-border-radius” and “-webkit-border-radius.” The former is how to specify the radius — number of pixels from a hypothetical center point to the edge of the circle created by the rounded corner (see the image below) — in Mozilla-based browsers. The latter is doing the same thing, but for Safari.
The rule isn’t just limited to curving background colors, either. If you were to add a border to the element, the border would become rounded, as well. For example, a block quote could be styled like so:
Resulting in a block quote that has a lot of style, without relying on images to accomplish the task:
And finally, you’re also not limited to either all rounded corners or none. Using this property, you can specify which corners you want rounded in your CSS. However, it’s important to note that the Firefox-based version of this rule has deviated a bit from the W3C standard, meaning it’s written slightly differently than the Safari-based rule. For example, consider these two rules used to round out the top-left corner of a box:
It’s a minor difference, in the grand scheme of things, but pretty critical if you want your rounded corners to show up where and how they should! Using the ability to round individual corners, you could generate fancy alert messages:
You can see all of my examples in action here. And these are just a few ways of the hundreds of ways you can harness the power of rounded corners with just a few lines of code. With techniques like this at our disposal, it’s easy to see why we’re all so eagerly awaiting CSS3!
The blockquote XHTML tag is a fairly useful (if somewhat underused) element. Semantically speaking, a blockquote should be used any time you’re quoting a longer piece of text from another source – another speaker, another website, whatever. It’s a way of setting the text apart, and showing that it came from some other source. Stylistically, you could accomplish all this with a special class on your paragraph tags… but that wouldn’t be as semantically useful, now, would it?
Blockquotes do have some styling by default. Most browsers will indent the text in a blockquote tag, which helps the user recognize that the text is different somehow. But who’s to say that we need to stop there? Here are six different ways you could style your blockquotes using CSS.
Color and Borders
Applying a color change to the text and adding a border (along with some additional margins and padding) can really make the blockquote stand out, yet is subtle enough to retain a hint of sophistication.
If you’d like something a little more obvious than just a text color change, you might considering altering your background color instead. This causes the blockquote to “pop,” making it immediately more noticeable. When applying background colors, be sure to account for any tags inside that might alter your margins (such as paragraph tags).
We’re also not just limited to colors! Many websites make use of background images in their blockquotes to help distinguish them from the surrounding text. The background image might appear below the text, or perhaps off to the side (like we’ve done here) by way of a wider left padding.
Borrowing from my Book-Style Chapter Introductions article, we can also distinguish our blockquotes by using drop-caps, stylized text, or (in this example’s case) both at the same time. Here, we’re making use of the first-letter and first-line pseudo-classes, so browser support may not be 100% in older browsers.
Or, if you’d rather go the subtle-but-effective route, you might consider altering the color of the text in the blockquote, as well as the font style or variant. Also in this example, I’m making use of the :before and :after pseudo-classes to insert content into my document – namely, the quotation marks at the beginning and end of the text. Of course, :before and :after aren’t supported by all browsers, so… caveat emptor, and all that.
There are lots of reasons you might want to offer your users more than one CSS file for your website. But whatever the reason, it's amazingly easy to create a function that swaps between multiple stylesheets using a few lines of jQuery. Read more →
