Really Simple Browser Detection with jQuery

For my Serious redesign, I push the envelope in terms of CSS’ advanced selector functionality. Stuff like: p:first-child p:first-child:first-letter p:first-child:after p:first-child:first-line Plus lots of other stylistic tricks that require CSS3 support in order to display as intended. Fortunately, most of the browsers to which I am catering with this new design have no problems with most of the advanced stuff. Of course, Internet Explorer chokes on just about everything, but fortunately IE’s proprietary conditional comments make it easy to fix things up with some “special” styles: Read more »

The New Clearfix Method

Say goodbye to the age-old clearfix hack and hello to the new and improved clearfix method.. The clearfix hack, or “easy-clearing” hack, is a useful method of clearing floats. I have written about the original method and even suggested a few improvements. The original clearfix hack works great, but the browsers that it targets are either obsolete or well on their way. Specifically, Internet Explorer 5 for Mac is now history, so there is no reason to bother with it when using the clearfix method of clearing floats. Read more »

Stupid WordPress Tricks

One of the most popular articles here at Perishable Press is my January 2005 post, Stupid htaccess Tricks. In that article, I bring together an extensive collection of awesome copy-&-paste HTAccess code snippets. Four years later, people continue to tell me how much they enjoy and use the content as a bookmarked reference for many of their HTAccess needs. The article was even published in a book on Joomla! Security. This is very inspiring to me, so I have decided to create a similar post for all of the useful WordPress code snippets, tips and tricks that I have collected […] Read more »

Getting Serious with a New Design

New design in effect at Perishable Press. It’s sort of a hybrid between some of the things I like about the Quintessential theme and some of the best parts of the subsequent Requiem theme. So this new theme is named Serious because it represents a renewed commitment to design, blogging, and everything I love about working on the Web. While I have everything fresh in my mind, here are some of the highlights of the latest incarnation of Perishable Press.. Read more »

Perfect Pre Tags

If you operate a website that features lots of code examples, you know how important it is to spend some quality time styling the <pre></pre> element. When left unstyled, wild <pre></pre> tags will mangle your preformatted content and destroy your site’s layout. Different browsers treat the <pre></pre> tag quite differently, varying greatly in their default handling of font-sizing, scrollbar-rendering, and word-wrapping. Indeed, getting your preformatted code to look consistent, usable, and stylish across browsers is no easy task, but it certainly can be done. In this article, I’ll show you everything you need to create perfect <pre></pre> tags. First thangs […] Read more »

Pimp Your 404: Presentation and Functionality

I have been wanting to write about 404 error pages for quite awhile now. They have always been very important to me, with customized error pages playing a integral part of every well-rounded web-design strategy. Rather than try to re-invent the wheel with this, I think I will just go through and discuss some thoughts about 404 error pages, share some useful code snippets, and highlight some suggested resources along the way. In a sense, this post is nothing more than a giant “brain-dump” of all things 404 for future reference. Hopefully you will find it useful in pimping your […] Read more »

Dressing up for Halloween..

Happy Halloween! This year, I thought it would be fun to dress up my site with one of its very first themes. The Lithium theme remains one of my favorites, despite some of the scary code used in a few of the template files. Even so, despite its relative simplicty, this theme features some great little details, and even features some stylish quicktags in the comments area. Incidentally, the Perishable Press logo was designed specifically for the Lithium theme way back in 2006. So enjoy this blast from the past! Hopefully it doesn’t scare anyone too badly.. Note: Thanks to […] Read more »


Time flies! Perishable Press celebrates its fourth year online during this Fall season. Not really sure what that means at this point, other than a lot of hard work, plenty of great conversation, and a ton of design-related content. How did I get here? Let’s take a brisk stroll down memory lane.. During the site’s first year, I remember being too excited for my own good. WordPress was relatively new and I was completely inspired by the amazing things I could do with it. I spent most of my time building all sorts of different themes, studying web design, and […] Read more »

Stupid Twitter Tricks

Might as well face it, Twitter is here to stay. Not that it’s all that bad, just used to be a lot more laid-back and enjoyable. These days it seems to have been taken over by the lowest common-denominator, mostly high-school twits or useless commercial propaganda. Even so, I still enjoy tweeting the occasional profound thought once in awhile, and even like to play around with various types of “advanced” Twitter functionality. You know, cool stuff like including “Tweet This!” links with short URLs, showing off my number of Twitter followers, displaying the number of tweets for each post, and even […] Read more »

HTAccess Privacy for Specific IPs

Running a private site is all about preventing unwanted visitors. Here is a quick and easy way to allow access to multiple IP addresses while redirecting everyone else to a custom message page. To do this, all you need is an HTAccess file and a list of IPs for which you would like to allow access. Edit the following code according to the proceeding instructions and place into the root HTAccess file of your domain: # ALLOW ONLY MULTIPLE IPs <limit GET POST PUT> Order Deny,Allow Deny from all Allow from 123.456.789 Allow from 456.789.123 Allow from 789.123.456 </limit> ErrorDocument […] Read more »

How to Protect Your Site Against Content Thieves

Stolen content is the bane of every blogger who provides a publicly available RSS feed. By delivering your content via feed, you make it easy for scrapers to assimilate and re-purpose your material on their crap Adsense sites. It’s bad enough that someone would re-post your entire feed without credit, but to use it for cheap money-making schemes is about as pathetic as it gets. If you’re lucky, the bastards may leave all the links intact, so at least you will get a few back-links (if you have been linking internally) and get notified of the stolen content as well […] Read more »

IDs are anchors, too.

While browsing the internet these days, I see a lot of this: <body> … <a name=”top”></a> … <a href=”#top”>- Back to Top -</a> … </body> There’s an easier, better and prettier way. CSS Signatures are all the rage these days. If you’re not familiar with a CSS Signature, it’s basically nothing more than an ID on your body tag, like this: <body id=”www-domain-tld”></body> The fundamental purpose of the CSS Signature is to allow a user to specify style adjustments to your site in their own user style sheets. Whether or not users are actually capitalizing on this is a discussion […] Read more »

Disable Trace and Track for Better Security

The shared server on which I host Perishable Press was recently scanned by security software that revealed a significant security risk. Namely, the HTTP request methods TRACE and TRACK were found to be enabled on my webserver. The TRACE and TRACK protocols are HTTP methods used in the debugging of webserver connections. Although these methods are useful for legitimate purposes, they may compromise the security of your server by enabling cross-site scripting attacks (XST). By exploiting certain browser vulnerabilities, an attacker may manipulate the TRACE and TRACK methods to intercept your visitors’ sensitive data. The solution, of course, is disable […] Read more »

Tell Google to Not Index Certain Parts of Your Page

There are several ways to instruct Google to stay away from various pages in your site: Robots.txt directives Nofollow attributes on links Meta noindex/nofollow directives X-Robots noindex/nofollow directives ..and so on. These directives all function in different ways, but they all serve the same basic purpose: control how Google crawls the various pages on your site. For example, you can use meta noindex to instruct Google not to index your sitemap, RSS feed, or any other page you wish. This level of control over which pages are crawled and indexed is helpful, but what if you need to control how […] Read more »

Sexy HTML List Tricks

Behold the ubiquitous list elements, <ul></ul> and <ol></ol>! These two sexy elements help millions of websites display lists of information in clean, semantic fashion. Without them, we’d be crawling around like filthy cavemen, eating dirt and howling at the moon. But these list elements aren’t just sexy, they are also extremely flexible, enabling us humble designers to create robust list configurations that are semantically versatile and highly customizable. We all know how to throw down a basic list: Read more »
