If you design wordpress themes, like me, you’ll sometimes start one of the default themes as a base. Editing a file of the theme would be okay, but would also wipe every change off once you update it. This is one of the worst mistakes you’ll make, and here is a way to prevent that as well.
My blog right here is a edit by me, of the theme Twenty Eleven by wordpressdotorg. The worst mistake I made while editing the theme is, to directly edit the CSS (and other) files.
Later, I learnt, that these changes would be lost once the theme is upgraded, which means all my hard work gone 🙁 I got a solution to that, though, I’ll have to code it again when it upgrades, but I’ll keep it in mind when I customize another theme.
The solution is to use wordpress child themes.Child themes are the recommend way to edit functionality of a wordpress theme. WordPress defines it as –
A WordPress child theme is a theme that inherits the functionality of another theme, called the parent theme, and allows you to modify, or add to, the functionality of that parent theme.
Creating a child theme may seem tough, but it is actually very easy. The only required file for a child theme is the style.css. Here’s how one should look –
/* Theme Name: NamanyayG Description: Child theme for the Twenty Eleven theme Author: Namanyay Goel Author URI: http: //www.namanyayg.com/ Template: twentyeleven */ @import url("../twentyeleven/style.css");
And that’s it! Actually, you only need the parts “Template :twentyeleven” and the “import”. Nothing else. Now go on, edit your wordpress themes in a safe and future secure way. Leave any questions in the comments.
