SEO Javascript - Calculate Title Google Pixel Length

Optimal

1. Best practice: Maximum title is between 466px and 469px (depending which browser & OS)

Code Example here:
https://jsfiddle.net/2at25hjh/

Html:

 <script src="https://code.jquery.com/jquery-2.1.4.js"></script>  
  <title>SEO Calculate The Title Google Pixel Length</title>  
 <body>  
 <input type="text" id="title" size="50" placeholder="Enter your page title here...">  
  <div id="placeholder"></div>  
 </body>  

Javascript:

 $(document).ready(function(){  
      $("#title").change(function(){  
           $(this).getGoogleWidth( $(this) );  
      });  
      $.fn.getGoogleWidth = function(obj){  
           var text = obj.val();  
           var google_css = 'color: #12C;cursor: pointer;display: inline;font-family: arial, sans-serif;font-size: 16px;font-weight: normal;height: auto;line-height: 19px;list-style-image: none;list-style-position: outside;list-style-type: none;margin-bottom: 0px;margin-left: 0px;margin-right: 0px;margin-top: 0px;overflow-x: visible;overflow-y: visible;padding-bottom: 0px;padding-left: 0px;padding-right: 0px;padding-top: 0px;text-align: -webkit-auto;text-decoration: underline;text-overflow: clip;visibility: visible;white-space: nowrap;width: auto;';

Visual Studio - Fix slow symbol loading in debug

Here is how I solved the "slow symbol loading" problem in Visual Studio 2012:

Go to Tools -> Options -> Debugging -> General

CHECK the checkmark next to "Enable Just My Code".

Go to Tools -> Options -> Debugging -> Symbols

Click on the "..." button and create/select a new folder somewhere on your local computer to store cached symbols. I named mine "Symbol caching" and put it in Documents -> Visual Studio 2012.

Click on "Load all symbols" and wait for the symbols to be downloaded from Microsoft's servers, which may take a while. Note that Load all symbols button is only available while debugging.

UNCHECK the checkmark next to "Microsoft Symbol Servers" to prevent Visual Studio from remotely querying the Microsoft servers.

Click "OK".

From now on, symbol loading should be much faster.

Note that if you make any changes/downloads to Microsoft assemblies, you may need to go back into the Symbols dialog box and "Load all symbols" again.
