I recently added to my growing library of image-preloading methods with a few new-&-improved techniques. After posting that recent preloading article, an even better way of preloading images using pure CSS3 hit me: .preload-images { background: url(image-01.png) no-repeat -9999px -9999px; background: url(image-01.png) no-repeat -9999px -9999px, url(image-02.png) no-repeat -9999px -9999px, url(image-03.png) no-repeat -9999px -9999px, url(image-04.png) no-repeat -9999px -9999px, url(image-05.png) no-repeat -9999px -9999px; } Using CSS3’s new support for multiple background images, we can use a single, existing element to preload all […] Continue reading »
Preloading images is a great way to improve the user experience. When images are preloaded in the browser, the visitor can surf around your site and enjoy extremely faster loading times. This is especially beneficial for photo galleries and other image-heavy sites where you want to deliver the goods as quickly and seamlessly as possible. Preloading images definitely helps users without broadband enjoy a better experience when viewing your content. In this article, we’ll explore three different preloading techniques to […] Continue reading »
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 […] Continue reading »
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 previously about the original clearfix 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 […] Continue reading »

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 […] Continue reading »
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 […] Continue reading »
![[ Screenshot: Default Apache 404 Error Page ]](https://perishablepress.com/wp/wp-content/images/2009/pimp-your-404/404-not-found.png)
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 […] Continue reading »
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. Continue reading »
![[ Content Thieves and Other Scumbags ]](https://perishablepress.com/wp/wp-content/images/2009/misc-chunks/content-thieves.jpg)
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 […] Continue reading »
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 […] Continue reading »
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 […] Continue reading »
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 […] Continue reading »
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: Continue reading »
Recently a reader asked about how to password-protect a directory for every specified IP while allowing open access to everyone else. In my article, Stupid htaccess Tricks, I show how to password-protect a directory for every IP except the one specified, but not for the reverse case. In this article, I will demonstrate this technique along with a wide variety of other useful password-protection tricks, including a few from my Stupid htaccess Tricks article. Before getting into the juicy stuff, […] Continue reading »

In my recent guest post at The Nexus, I discuss Google’s new nofollow policy and suggest several ways to deal with it. In that article, I explain how Google allegedly has changed the way it deals with nofollow links. Instead of transferring leftover nofollow juice to remaining dofollow links as they always have, Google now pours all that wonderful nofollow juice right down the drain. This shift in policy comes as a terrible surprise to many webmasters and SEO gurus, […] Continue reading »
Anyone plugged into the Web these days has heard about how Google has supposedly changed the way it deals with nofollow attributes. According to a number of speculative reports, Google will no longer apply unused nofollow PageRank to other links on the page. So, let’s say that you have some sites that have been PageRank “sculpted” by way of strategically applied nofollow tags. For example, you may have nofollowed all of your comment, footer, or sidebar links. Ever since Google […] Continue reading »
