All CSS Filter Functions + Quick Copy/Paste Examples

CSS makes it easy to customize image appearance on the fly. So you don’t have to crank open your image editor and do any work there. You can apply many visual effects directly on the image using the CSS filter property. You can change image brightness, contrast, opacity, saturation — even do things like rotate hues, drop shadows, and blur the image. Browser support is solid for all major browsers.

New Book: Wizard’s SQL Recipes for WordPress

I’m excited to launch my latest web-dev book, Wizard’s SQL Recipes for WordPress. I got the idea for this book way back when I was first learning how to build dynamic websites. I thought it would be useful to bring together all of the best SQL snippets in sort of a “spellbook” or “cookbook”. After all, SQL queries can seem like magic to the uninitiated. By entering concise, well-crafted commands, SQL enables anyone to interact with any relational database. It’s […] Continue reading »

Code Snippets to Customize WordPress Sitemaps (Complete Guide)

By now most have heard about the WP Sitemaps feature introduced in WordPress version 5.5. From what I’ve read most existing sites that needed a sitemap already had one via one of the many free sitemap plugins. But for new WordPress sites going forward, having all the sitemap code in the WordPress core now means that new sites have the option of rolling with the default WordPress sitemaps, or use a dedicated plugin to do the job. This post is […] Continue reading »

X Theme Leftover Code Snippets

While working on the site’s 24th redesign, I ended up with about 10 code snippets that were awesome but ultimately not needed. So rather than just delete these tasty functions, I am posting them here for future reference. Who knows, during the next site update I may decide to implement or repurpose some of these techniques. And of course sharing is caring, so feel free to use any of these code snippets in your own projects. Check out the Table […] Continue reading »

s2member notes

I use s2member (free version) and s2member Pro on a few of my sites. Have been for several years now. Over the course of time, I have amassed a healthy collection of notes, code snippets and techniques for customizing default functionality, adding features, and so forth. Gonna post the collection online for the benefit of any others who may be seeking for similar modifications and/or related information. Continue reading »

WP-Mix – A fresh mix of code snippets and tutorials

Wrapping up 2012, I finally launched xyCSS, which is all about responsive, grid-based design. To showcase xy.css, I used it to design WP-Mix.com, which also serves to house a growing collection of choice code snippets. Currently WP-Mix features over 100 snippets, tutorials, and other useful bits to help with WordPress development and web design in general. The topics are similar to those at Perishable Press (e.g., WordPress, PHP, JavaScript, CSS, etc.), but the posts are less-involved and aimed at intermediate […] Continue reading »

PHP Tip: Encode & Decode Data URLs

Converting small images to data-URLs is a great way to eliminate HTTP requests and decrease loading time for your pages. Using PHP‘s base64_encode() and base64_decode() functions, we have the power to convert images to data-URLs and vice-versa. This article explains how it all works, and shows some different ways of converting back and forth between original and encoded images. Continue reading »

CSS3 Tip: Removing Box Shadows

Adding box shadows is a great way to bring depth and focus to your design. You have probably seen this trick before: .selector { -webkit-box-shadow: 0 3px 5px #333; -moz-box-shadow: 0 3px 5px #333; box-shadow: 0 3px 5px #333; } Continue reading »
