Prevent Widows with PHP and JavaScript
One of the small touches you can add to your website is preventing "widows" in your H1-H6 tags. For those who aren't aware, a widow (in terms of text and headings) means only one word of a title wraps to the next line -- a bit of an ugly sight if you ask me. The way to prevent widows with just text is by adding a between the last two words of the text instead of a regular space character. Here are two snippets for preventing widows in your website: one using JavaScript and another using PHP!
// With JavaScript
var text = text.replace(/\s(?=[^\s]*$)/g, ' ');
// With PHP
$text = preg_replace( '|([^\s])\s+([^\s]+)\s*$|', '$1 $2', $text);
As I mentioned originally, widows are not necessarily a bug, but a small visual quirk that just doesn't look great. Keep these regex usages handy so you can prevent such a smudge!

![Cross Browser CSS Box Shadows]()
Box shadows have been used on the web for quite a while, but they weren't created with CSS -- we needed to utilize some Photoshop game to create them. For someone with no design talent, a.k.a me, the need to use Photoshop sucked. Just because we...
![Pure CSS Slide Up and Slide Down]()
If I can avoid using JavaScript for element animations, I'm incredibly happy and driven to do so. They're more efficient, don't require a JavaScript framework to manage steps, and they're more elegant. One effect that is difficult to nail down with pure CSS is sliding up...
Great idea to take care of all headings at once!
Only concern I would have would be search engines. Are there repercussions to adding this markup? Would it confuse/deter proper search engine indexing?
I’m sure Google, etc take javascript into account in some way, but I would do this via javascript instead of PHP to lessen the chances of hurting search rankings (if that’s important to you).
I’ve never seen the ?= operator in regular expression. And I don’t find such in my regex cheat sheet. Can you please explain how this particular reg ex is working? Thanks.
The
?=is a look-ahead operator. It allows you to specify an expression that matches what comes next. In the example abovethe expression is stating that the character after the space must be zero-or-more non-whtie-space characters followed by the end of the string. In other words, it makes sure that it only replaces the last space in the heading with a non-breaking space.
