CSS Hack: Opacity on IE

If you want to get opacity to work on all IE browsers, use the following IE filters in the order:
.opaque {
  -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=50)"; // for IE8/9
  filter: alpha(opacity=50);  // for IE5-7
  opacity: .5;  // for all other browsers    
}

Note: opacity gets inherited by child elements. So it's better to use background-color:rgba(r,g,b,alpha). For IE browsers, use gradient filter with #argb.

    It's a good hack for IE in general, however, it may not be required for IE5 and IE 5.5 anymore.

How to resolve 'res://ieframe.dll/acr_error.htm#' error (Internet Explorer stopped working while viewing a website)

While testing a website I was developing, I got an error message saying "Internet Explorer has stopped working". This is followed by this line added before the URL: res://ieframe.dll/acr_error.htm# . I was using Internet Explorer 11 in Windows 7 64-bit machine. I tried disabling all add-ons in IE but that did not resolve the issue. I've found this solution to my problem: From Tools menu, open "Internet options". Go to the Advanced tab. Under "Accelerated graphics", tick the box that says "Use software rendering instead of GPU rendering". Click Apply and Ok. Test your website. You might need to restart your computer if it does not immediately show any effect. This worked for me.

htaccess: Redirecting multiple domains to the main domain

Let's say this is the main domain: mywebsite.com.au And you'd like to redirect several other domains that you have purchased to this main domain.The steps shown below redirects all www, non-www, http and https variations and also matches the internal pages. Step 1: Go to your DNS provider's website and point each of those purchased domains to the server that is hosting your main domain. In other words, add the IP address of your hosting server in the A record. Step 2: Log in to your WHM. Then park each domain on top of the main domain. You may be able to do this in cPanel > Aliases but I haven't tried. Step 3: If you have AutoSSL enabled, all the additional parked domains will automatically get SSL added. This may take some time. Alternatively, you can go to WHM > Manage AutoSSL and Run AutoSSL Check. Step 4: Add your parked domains to your .htaccess file as shown below. Note the "$" at the end of this line: ^www\.mywebsite\.com$ . This ...
