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 »

Computer Flashback: Windows 98 Run Commands

Even with all the fancy-pants new features found in Windows XP and now Vista, Microsoft Windows 98 (Second Edition) remains our favorite Windows-flavored operating system. We love it so much, we still use it on one of our trusty laptops. Over the years, we have discovered several very useful functions available via the command line or even the “Run” prompt (Start → Run…). Anyway, without spending too much time researching or explaining these wonderful tools, we figured posting the information online may prove beneficial at some point in the future. So, without further ado, we present this working repository of helpful MS […] Read more »

Smooth Operators: Sharpen your Google Search Skills

Coming soon to the World Wide Web: Everything. The perpetually evolving sum of human knowledge available online. Anywhere. Anytime. So, what are you looking for? Information concerning something, somewhere, about somebody.. You know it’s there somewhere. Sure, you could waste time by digging through that immense labyrinth of browser bookmarks, maybe eventually finding that one link that may or may not lead you to the page that you remember.. No thanks. The Web is far too rich in information to limit it with a few bookmarks. Ah yes, tags — that’s it! Social bookmarking to the rescue. Okay now, let’s […] Read more »

Search Engine Registration Notes

In his excellent book, Search Engine Optimization for Dummies, Peter Kent explains that many search engines actually get their search results from one (or more) of the larger search engines, such as Google or The Open Directory Project. Therefore, the author concludes that it may not be necessary to spend endless hours registering with thousands of the smaller search sites. Rather, the author provides a brief list of absolutely essential search sites with which it is highly recommended to register. Further, by registering with the following sites, your site will be listed in a significant majority of all search engines. Read more »

URL Character Codes

URL’s frequently employ potentially conflicting characters such as question marks, ampersands, and pound signs. Fortunately, it is possible to encode such characters via their escaped hexadecimal ASCII representations. For example, we would write "?" as "%3F". Here are a few more URL character codes (case-insensitive): Read more »

Hide Content on Windows 98SE

This brief tutorial on hiding content applies to Windows 95, 98, and 98SE. Although this method may be old hat or even irrelevant, I have found it useful on a number of occasions, and therefore found it worthwhile to include here for the sake of prosperity. On Windows 98SE (and others), it is possible to create a folder that is both listed and inaccessible via the Windows file system. Using an old DOS trick involving an obscure character reference, we create a folder that, when clicked on via Windows, produces a "The File does not Exist" error message, thus denying […] Read more »

Fun with the DOS Command Prompt

Note: This article assumes a basic familiarity with the DOS command prompt, and is somewhat of a continuation of our previous article on DOS, Basic DOS Commands. Here, we are exploring a few of the more interesting commands available via the DOS command prompt. For a more complete reference please consult the Windows Help file (Windows XP) by entering hh.exe ms-its:C:\WINDOWS\Help\ntcmds.chm::/ntcmds.htm at the command line prompt (or via the Start > Run… dialogue box). For a brief overview of essential DOS commands, characters, devices, and variables, check out DOS Fundamentals. Read more »

DOS Fundamentals

A brief overview of essential DOS commands, characters, devices, and variables Ahh, the fun I have at work while experimenting with the command line. I will be the first to admit that I understand very little of DOS, especially when considering the scope of its functional capacity. Nonetheless, I am taking the time to chronicle a few interesting DOScoveries here in this article, as well as in at least a couple of others (see related articles section at the end of this article). The first thing that I should mention is that there are at least several different entities commonly […] Read more »

Industrial-Strength Spamless Email Links

In our previous article on creating spamless email links via JavaScript, the presented method, although relatively simple to implement, is not the most effective solution available. Spambots, email harvesters, and other online scumbags relentlessly advance their scanning technology, perpetually rendering obsolete yesterday’s methods. In the case of spamless email links created client-side via JavaScript, many spambots now are able to decipher certain email addresses hidden within the JavaScript code itself. Spambots scan JavaScript for keywords such as "email" or "mail", or even character strings containing ".com" or the "@" symbol. Spambots collect and decipher such data and return the favor […] 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 »

Embed External Content via iframe and div

By using an <iframe></iframe> within a <div></div>, it is possible to include external web content in most any web document. This method serves as an excellent alternative to actual frames, which are not as flexible and definitely not as popular. Indeed, with CSS, the placement, sizing, and styling of div’s provides endless possibilities for embedding external or even internal web content into pages that would otherwise require the use of frames, Flash, or JavaScript. This method works on any modern browser, as well as any old browser that understands both <div></div> and <iframe></iframe> tags. Simply add the following code to […] Read more »

Greenwich Mean Time (GMT) Formats

There are currently three formats for expressing date/time in Greenwich Mean Time (GMT). All examples represent the date, "July 04, 2050". The time for all three formats is expressed as "hour:minutes:seconds". Here is the preferred, standard format1 for the Internet. This format is defined by RFC 1123 (updated from RFC 822): # RFC 1123 Standard GMT Format Mon, 04 Jul 2050 07:07:07 GMT The programming language C uses the ANSI standard format1 in its asctime(): # ANSI Standard GMT Format Mon Jul 4 07:07:07 2050 The RFC 850 format2 is now obsolete (RFC 1036) and should not be used: # […] Read more »
