  • CSS relative positioning issue

    Issue: The uploaded images are stored in sites->all->defaults->files instead of sites->all->defaults->files->imagecache->[preset subdirectories].

  • Browser detection - IE, Firefox, Safari, Chrome

    Many times you require to put in browser-specific HTML / CSS in your files, because most often the pages are rendered differently (esp. IE). You can detect what browser the user is using with the help of PHP. In your PHP file, put the following code first:

    1. <?php
    2. $msie = strpos($_SERVER["HTTP_USER_AGENT"], 'MSIE') ? true : false;
    3. $firefox = strpos($_SERVER["HTTP_USER_AGENT"], 'Firefox') ? true : false;
    4. $safari = strpos($_SERVER["HTTP_USER_AGENT"], 'Safari') ? true : false;
    5. $chrome = strpos($_SERVER["HTTP_USER_AGENT"], 'Chrome') ? true : false;
    6. ?>
