XHMTL/CSS Remix: Creative Commons License

Not too long ago, I played with the idea of releasing article content under a Creative Commons (Attribution-NonCommercial-ShareAlike 2.0) License. At the time, I wanted to host my own copies of the two associated CC license pages. During the process of uploading the pages to my own server, several minor adjustments (regarding image paths, etc.) needed to be made to the source code. After tweaking a few things in the XHTML code, I began snooping around in the pages’ CSS files. Eventually, I found myself rewriting the entire CSS and XHTML files for both documents. Although this sort of activity […] Read more »

Perishable News: Site Upgrades, Upcoming Interview, and PageRank Update

Ever since writing that last review article, I have been feeling the need to cut loose, relax, and blog about something a little more “down-to-earth,” like recent things that have been happening around here. If you are new to Perishable Press, rest assured that I try to keep these “site/personal news” update posts down to a minimum. Whenever possible, I save up a bunch of interesting off-topic things that I want to talk about, and then cram them all together into a multipurpose article like this one. I have found that consolidating and summarizing multiple news items into one post […] Read more »

Lessons Learned Concerning the Clearfix CSS 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. Over the course of the past few years, I have taken note of several useful bits of information regarding the Easy Clear Method. In this article, I summarize these lessons learned and present a (slightly) enhanced version of the clearfix hack.. Read more »

Coldskins: Custom CSS Skins for Contact Coldform

Update (2012/11/08): Contact Coldform is updated with new built-in “coldskins” and option to add your own custom styles. The coldskins on this page still work for previous versions of the Coldform, but are replaced by the built-in styles for version 20121031+. With the recent release of my latest WordPress plugin, Contact Coldform, I am also creating a series of free, “drop-in” CSS skins for easy, “plug-n-play” customization. These skins employ valid, optimized CSS code designed for the following browsers: Firefox 2 (mac & pc) Internet Explorer 6 Internet Explorer 7 Opera 9 (mac & pc) Netscape Camino Safari The goal […] Read more »

Prevent JavaScript Elements from Breaking Page Layout when Following Yahoo Performance Tip #6: Place Scripts at the Bottom

By now, everyone is familiar with the Yahoo Developer Network’s 14 “best-practices” for speeding up your website. Certainly, many (if not all) of these performance optimization tips are ideal for high-traffic sites such as Yahoo or Google, but not all of them are recommended for smaller sites such as Perishable Press. Nonetheless, throughout the current site renovation project, I have attempted to implement as many of these practices as possible. At the time of this writing, I somehow have managed to score an average 77% (whoopee!) via the YSlow extension for Firebug. Of the handful of these tips that I […] Read more »

New Mobile CSS Styles for Perishable Press

The amount of time I spend surfing the Web from a mobile device has steadily increased since the acquisition of my new favorite mobile device. Unfortunately, many sites have yet to implement (or even consider) support for mobile devices. Without proper formatting, such sites are virtually useless, requiring unnecessary download times, displaying unreadable pages, and serving unusable content. Given the inevitable ubiquity of mobile access to the World Wide Web, providing reasonable support for handheld browsers is becoming increasingly important. Without it, your site is left looking incomplete and unprofessional when viewed from mobile devices. So, with that said, today […] Read more »

Killer Collection of CSS Resets

Update! Check out CSSresetr for an easy way to test and download the best reset styles for your next design. Using CSS to style semantically meaningful (X)HTML markup is an important key to modern web design practices. In a perfect world, every browser would interpret and apply all CSS rules in exactly the same way. However, in the imperfect world in which we live, quite the opposite frequently happens to be the case: many CSS styles are displayed differently in virtually every browser. Many, if not all, major modern browsers (e.g., Firefox, Opera, Internet Explorer, Netscape, et al) implement their […] Read more »

Miscellaneous Happenings

Many changes around here lately — new styles, new software, new hardware, and a whole lot more. I will be covering several of these items in greater depth in future posts, but for now, here is an overview of some of the recent happenings unfolding here in Perishable land.. New Mobile Styles I finally took the time to throw down some tuff mobile CSS styles for Perishable Press. Before, the site was virtually impossible to use via mobile devices because of the comprehensively applied screen styles, which completely overwhelm the screen real-estate and system resources of the average mobile device.

Absolute Horizontal and Vertical Centering via CSS

Recently, a reader named Max encountered some scrolling issues while implementing our absolutely centered layout technique. Of course, by “absolutely centered” we are referring to content that remains positioned dead-center regardless of how the browser is resized. After noticing the scrollbar deficiency, Max kindly dropped a comment to explain the issue: …the div solution works well, only one problem maybe somebody can help: if you make the browser window smaller then the div is -> the scrollbar doenst fit right und you cant scroll over the whole area… Apparently, because the horizontal/vertical centering method outlined in our original article employs […] Read more »

CSS Throwdown: Preload Images without JavaScript

Clean, easy, effective. You don’t need no stinking JavaScript to preload your images. Nope. Try some tasty CSS and (X)HTML instead! Here’s how.. (only two steps!) Step 1 — Place this in your CSS file: div#preloaded-images { position: absolute; overflow: hidden; left: -9999px; top: -9999px; height: 1px; width: 1px; } Step 2 — Place this at the bottom of your (X)HTML document: <div id=”preloaded-images”> <img src=”http://perishablepress.com/image-01.png” width=”1″ height=”1″ alt=”” /> <img src=”http://perishablepress.com/image-02.png” width=”1″ height=”1″ alt=”” /> <img src=”http://perishablepress.com/image-03.png” width=”1″ height=”1″ alt=”” /> </div> ..and that’s a wrap! All images are preloaded and ready for calling as you please. Completely valid, […] Read more »

Standards-Compliance Throwdown: MS-IE5/6 DNS/404 Error-Page Redesign

Default DNS Error page for Internet Explorer First of all, congratulations if you are geeky enough to understand the title of this article. Many would be like, "CSS, MS.. IE, error ..what..?" Whatever. If you get the title, you will get the point of this utterly pointless exercise. If that is the case, prepare for a delightful romp through geekland. Otherwise, save your precious time and stop reading here (exit strategy). Well, okay, for the seriously unenlightened, let us explain the object of our present focus: The default "DNS Error" page for Internet Explorer unfortunately remains a familiar sight for millions […] Read more »

Maximum and Minimum Height and Width in Internet Explorer

Behold the seventh wonder of the virtual world: max/min-height and max/min-width properties are possible in Internet Explorer! Indeed, by taking advantage of IE’s proprietary CSS attribute, expression, you too can whip IE widths and heights into desirable proportions. The CSS expression attribute enables JavaScript commands to be executed within Internet Explorer. JavaScript via CSS? Thanks, Microsoft! Why is this so great? Well, because in other, standards-compliant browsers, max/min-height and max/min-width properties are easily accomplished with this simple bit of CSS.. Read more »

Keep it Dark: Hiding and Filtering CSS

Hiding and filtering CSS rules for specifically targeted browsers is often a foregone conclusion when it comes to cross-browser design considerations. Rather than dive into some lengthy dialogue concerning the myriad situations and implications of such design hackery, our current scheduling restraints behoove us to simply cut to the chase and dish the goods. Having said that, we now consider this post a perpetually evolving repository of CSS filters.. Read more »

Preloading Images with CSS and JavaScript

Fast-loading pages reduce errors, conserve bandwidth, and please visitors. One way to decrease loading times and enhance performance involves maximizing image display efficiency. Your mantra for achieving image efficiency should be "reuse, optimize, and preload.". While each of these methods plays an important role, this article will focus on methods for preloading images. Consult your server error logs to identify web pages that may require image help. Note: preloading images does not reduce bandwidth! It only decreases apparent load time, thereby enhancing user experience. Preloading via the CSS Display Property This method is a very common method for preloading images […] Read more »

Firefox CSS Magic

Consider this post an evolving receptacle for Firefox-specific CSS tricks. Change the color of highlighted text *::-moz-selection { background: #FF3C00; /* the background color of the highlight */ color: #FFF; /* the color of the text within the highlight */ } Change the opacity of an element div#division { /* choose either attribute */ -moz-opacity: 0.99; /* possible values: 0-1 */ -moz-opacity: 99%; /* possible values: 0%-99% */ } Control item selection of an element div#division { /* choose one of the following values */ -moz-user-select: none; /* no content within the element may be selected */ -moz-user-select: all; /* […] Read more »
