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 »

Ever since Internet Explorer 5 (IE5), Microsoft has included browser support for “downlevel conditional comments”, a non-scripted method of browser detection. Downlevel conditional comments (DCC) are a useful tool for targeting directives to specific versions of Internet Explorer. Downlevel conditional comments consist of an opening statement and a closing statement. Taken together, the statements may enclose markup, CSS, JavaScript, or any other element typically included within an (X)HTML document. The DCC may be placed anywhere within the document and executes […] Continue reading »

Search engines loathe crawling through convoluted lines of code. Oceans of complex JavaScript scare away the priceless indexing and archiving efforts of most major search engines, which will generally abort a crawl upon encountering such mess. The good news is that search engines actually do not deploy JavaScript, so it is possible to use JavaScript to hide those miles of messy code by using the fundamental document.write function.

The […] Continue reading »

I love looking at beautiful source-code output. However WordPress tends to spit code out in random chunks, often leaving spaces, line breaks, and tabs littered throughout the source output. This messes things up. Lists don’t look like lists and logically written code often appears scattered along the page carelessly. Often, this is the result of poorly written PHP, which can be manipulated to write beautifully aligned code that looks as good as it works. Continue reading »
