Content Negotiation for XHTML Documents via PHP and htaccess

[ Content Negotiation ]

In this article, I discuss the different MIME types available for XHTML and explain a method for serving your documents with the optimal MIME type, depending on the capacity of the user agent. Using either htaccess or PHP for content negotiation, we can serve complete, standards-compliant markup for our document’s header information. This is especially helpful when dealing with Internet Explorer while serving a DOCTYPE of XHTML 1.1 along with the recommended XML declaration. According to the RFC standards1 produced […] Continue reading »

CSS/(X)HTML Tutorial: Hovering Accessibility Jump Menu

[ Jump Menu ]

Recently, a reader named Don asked about this theme’s accessibility (accesskey) jump menu located at the top of each page. Several people have commented that they like the way the jump menu “lights up” upon gaining focus. Whenever a user hovers their cursor over the region at the top of the page, all links in the jump menu change to a more visible color. Then, as the cursor moves over the various menu items, each jump link is further highlighted […] Continue reading »

XHMTL/CSS Remix: Creative Commons License

[ Screenshot: Creative Commons Deed - Remixed ]

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 […] Continue reading »

What is the Difference Between XHTML 1.0 Strict and XHTML 1.1?

As some of you (e.g., Louis) may have noticed during the recent site redesign, I decided to switch the default doctype from XHTML 1.0 Strict to XHTML 1.1. Just in case you were wondering, XHTML 1.1 is different than XHTML 1.0 in three important ways1: On every element, the lang attribute has been removed in favor of the xml:lang attribute On the a and map elements, the name attribute has been removed in favor of the id attribute The “ruby” […] Continue reading »

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

[ Screenshot: broken footer positioning in IE 7 ]

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 […] Continue reading »

Position Absolute Horizontal and Vertical Center 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 […] Continue reading »

Rethinking Structural Design with New Elements in HTML 5

[ Image: Tyrannosaurus Skull ]

HTML 5, also known as Web Applications 1.0, provides new markup elements that will change the way you design your web pages. The new elements replace commonly used divisions in web documents, facilitating an even greater degree of separation between structure (HTML) and presentation (CSS). Indeed, in many documents, the new elements will structure the document while providing enough hooks to render obsolete previously required divisions, classes, and identifiers. Let’s take a look..

Essential HTML Entities

[ Image: Two Hip Characters ]

Virtually every article written here at Perishable Press requires at least one or two “special” HTML characters. Some of these characters — such as quotation marks, hyphens, and dashes — are very common, while others — such as the copyright symbol, bullet, and arrow — happen less frequently. The vast majority of special characters, however, like the latin Ä (i.e., capital letter “A” with a diaeresis), and the mathematical symbol ⊃ (i.e., superset), rarely see the light of day on […] Continue reading »

The Friendliest Link Targets in the Neighborhood

[ Image: Fred Rogers with Shoe ]

The target attribute for anchor elements (<a></a>) specifies the location in which the referenced document should load. For example, to open a link in a new window, we would use a target value of _blank. Although this is a commonly employed technique, the target attribute has been deprecated by the W3C and is not valid (X)HTML. Regardless, the target element remains a useful tool for practicing designers and developers. Here, we present the attribute values for the target element: Continue reading »

URL Character Codes

URLs 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), for easy copy/paste reference. Continue reading »

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 […] Continue reading »
