Series Summary: Minimalist Web Design Showcase

Here at Perishable Press, I love to write about minimalism, simplicity, and usability in user-interface and web design. I have always enjoyed the minimalist aesthetic, as my Perishable Theme plainly illustrates. Fortunately, many designers and developers have embraced the minimalist concept, and continue to produce and promote minimalist design principles in their designs. As often as my schedule allows, I like to take the time to explore and share some of my favorite minimalist designs, and so far have managed […] Continue reading »

Evil Incarnate, but Easily Blocked

As my readers know, I spend a lot of time digging through error logs, preventing attacks, and reporting results. Occasionally, some moron will pull a stunt that deserves exposure, public humiliation, and banishment. There is certainly no lack of this type of nonsense, as many of you are well-aware. 3G Blacklist Even so, I have to admit that I am very happy with my latest strategy against crackers, spammers, and other scumbags, namely, the 3G Blacklist. Since implementing this effective […] Continue reading »

Beware of Margins or Padding when Using the min-width Hack for IE

While we all watch as Internet Explorer 6 dies a slow, painful death, many unfortunate designers and developers continue to find themselves dealing with IE6’s lack of support for simple things like minimum and maximum widths. Fortunately, there are solutions to this problem, primarily in the form of CSS expressions such as this: /* set the minimum width for IE 6 */ #target_element { width: expression((document.body.clientWidth < 335)? "333px" : "auto"); /* min-width for IE6 */ min-width: 333px; /* min-width […] Continue reading »

Yahoo! Once Again Caught Disobeying Robots.txt Rules

Hmmm.. Let’s see here. Google can do it. MSN/Live can do it. Even Ask can do it. So why oh why can’t Yahoo’s grubby Slurp crawler manage to adhere to robots.txt crawl directives? Just when I thought Yahoo! finally figured it out, I discover more Slurp tracks in my Blackhole trap for bad spiders: Continue reading »

Use Your Browser to Edit Any Live Web Page Using a Single Line of JavaScript

This was just too juicy to pass up. Blogstorm recently blogged about an easy JavaScript technique for making any website editable. After checking it out for myself, I just had to share it here at Perishable Press. Here it is: javascript:document.body.contentEditable='true'; document.designMode='on'; void 0 Paste that single line of code into the address bar of any modern browser and have fun editing the page. Obviously, any changes will only apply to the page as seen in your browser, not the […] Continue reading »

CSS Hackz Series: Targeting and Filtering Internet Explorer 7

Continuing the CSS Hackz Series, I present a small army of hacks for targeting and filtering Internet Explorer 7! Here, “targeting” IE 7 means to deliver CSS and/or (X)HTML to IE 7 only, while “filtering” means to deliver CSS and/or (X)HTML to every browser that is not IE 7. In other words, targeting is to include (apply), filtering is to exclude (hide). Let’s dive right in.. Continue reading »

Provide a Link for Visitors to Verify Your Feedburner Subscriber Count

[ Count Chimpula ]

Recently, I received a bizarre email accusing me of calling someone out on their fake Feedburner subscriber count. Apparently, some desperate blogger had been claiming to have something like 30,000 Feedburner subscribers when in reality they only had around 700. From what I could tell, the fraudulent site was displaying a counterfeit Feedburner subscriber-count badge using some fancy CSS image-replacement or something. Whatever. I really could care less, but the information contained in the email got me thinking: Providing an […] Continue reading »

CSS Hackz Series: Clearing Floats with the Clearfix Hack

I use the CSS clearfix hack on nearly all of my sites. The clearfix hack — also known as the “Easy Clearing Hack” — is used to clear floated divisions (divs) without using structural markup. It is very effective in resolving layout issues and browser inconsistencies without the need to mix structure with presentation. There are countless variations of the clearfix hack around the Web, and for some sad reason, I keep a file updated with all of them. Recent […] Continue reading »

Does Google Hate Web Standards?

[ Thumbnail: Google W3C Invalidation ]

Consider the Google home page — arguably the most popular, highly visited web page in the entire world. Such a simple page, right? You would think that such a simple design would fully embrace Web Standards. I mean, think about it for a moment.. How would you or I throw down a few lists, a search field, and a logo image? Something like this, maybe: Continue reading »

Quick Reminder About Downlevel-Revealed Conditional Comments..

As more and more people discover the flexibility, specificity, and all-around usefulness of Microsoft’s proprietary downlevel conditional comments, it behooves us to reiterate the importance of utilizing proper syntax. Specifically, for downlevel-revealed, or negative, conditional comments, the commented content will remain visible unless the associated if condition proves false. Continue reading »

How to Cache Mint JavaScript

[ Mint Icon ]

Recently, I spent some time addressing a few of the performance issues pointed out by Yahoo!’s very useful YSlow extension for Firebug. Working on performance tip #3, Add an Expires or a Cache-Control Header, I encountered some difficulty while trying to get the JavaScript used by Mint to cache as desired. Apparently, the HTAccess directives used to cache my other scripts do not effect the two PHP-generated JavaScript files used by Mint. Although I am not entirely certain, I suspect […] Continue reading »

Sharpen Your Site by Removing Unwanted Link Border Outlines

[ Thumbnail: Link Outline Example 01 ]

Lately I have noticed several sites that display those unsightly dotted outlines on high-profile link elements. Typically, these link outlines plague various header elements such as banner images, navigational links, and other key features. This behavior frequently haunts highly graphical site designs and is often associated with various image replacement methods that position the original anchor text offscreen, generally far beyond the left edge of the browser window. When visible, such presentations display a ghastly, four-sided dotted border that wraps […] Continue reading »

Unexplained Crawl Behavior Involving Tagged Query Strings

I need your help! I am losing my mind trying to solve another baffling mystery. For the past three or four months, I have been recording many 404 Errors generated from msnbot, Yahoo-Slurp, and other spider crawls. These errors result from invalid requests for URLs containing query strings such as the following: https://example.com/press/page/2/?tag=spam https://example.com/press/page/3/?tag=code https://example.com/press/page/2/?tag=email https://example.com/press/page/2/?tag=xhtml https://example.com/press/page/4/?tag=notes https://example.com/press/page/2/?tag=flash https://example.com/press/page/2/?tag=links https://example.com/press/page/3/?tag=theme https://example.com/press/page/2/?tag=press Note: For these example URLs, I replaced my domain, perishablepress.com with the generic example.com. Turns out that listing the plain-text […] Continue reading »

CSS Hackz Series: PNG Fix for Internet Explorer

In this CSS Hackz Series article, I outline several solutions for displaying alpha-transparent PNG (a.k.a. PNG–24 format) images in everybody’s favorite broken browser, Internet Explorer. Specifically, IE versions through 6 (excluding IE 5 for Mac) fail to support alpha-channel transparency for PNG images. In these versions of IE, every pixel containing alpha-transparency is displayed with an ugly, flat gray color. Fortunately, there are plenty of hacks and workarounds designed to “fix” IE’s PNG image-display problem. Unfortunately, every currently available solution […] Continue reading »
