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, '?');
Salin selepas log masuk
// With PHP
$text = preg_replace( '|([^\s])\s+([^\s]+)\s*$|', '$1?$2', $text);
Salin selepas log masuk

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!
