  1. Using the main scrollbar to scroll an iframe

    If we want to use the browser's scrollbar to scroll the content of an iframe, we must do the following:
    1. calculate iframe's offsetHeight + pixel distance of top of iframe with respect to top of main window + pixel distance of bottom of iframe with respect to bottom of main window ;
    2. give the main window a pixel height that is identical to the result of that calculation;

  2. PHP Stylesheet/Content Switcher with Save Cookie

    Here is a simple PHP script to change stylesheets or load in alternative content (conditional loading), with cookies to store user selection.

    The nice thing about a PHP-based solution over JavaScript content/CSS switchers, is that all the checking and switching is done on the server side, before the web page even finds it's way to the browser, so you don't get any flash of unstyled content. Plus, you can conditionally load HTML or external files (improve performance and save on load ...
  3. Embedding and programmatically controlling multiple YouTube videos

    We can embed and programmatically control multiple YouTube videos by putting onloads like the following in (existing) iframes:
    onload="player1=new YT.Player(this)"
    onload="player2=new YT.Player(this)"

    etc.

  4. Multi-Level, Off-Canvass Menu with IE7/8 support

    Hidden side menus, like the ones used in Facebook and Youtube apps, are a space-saving alternative to traditionally visible desktop menus. This post introduces an upgrade to the earlier CSS-only off-canvass menu, that makes it possible for IE7/8 users to enjoy this menu too.

    All the features are the same as the CSS-only version - the difference here is that JavaScript makes it compatible with earlier versions of Internet Explorer (IE7/8).

  5. Creating a rt-editor without installing software. Adding php for saving the edits.

    It's not easy to find a good rich text editor on the internet that:
    1. explains in comprehensive terms how to save the edits online, that is, how to send them to the server (or that at least uses clear instructions on how to do it);
    2. does not require that software be installed on your hard disc.

    So I created my own personal file explaining (to myself) how to achieve 1 and 2 above. Some of you may be interested in it, so here's the result. You can find all the explanations ...
