HTML Error on Coding

Hi Everyone,

I have syntax errors in this source coding that I can't seem to find an answer to.  I have something indicated wrong in the coding.

The Coding:  <div style="background-color: #000000; filter: progid DXImageTransform.Microsoft.Alpha(opacity=40) progid: DXImageTransform.Microsoft.Blur(pixelradius=3); height: expression(this.nextSibling.offsetHeight); width:expression(this.nextSibling.offsetWidth); left: 3px; top: 3px; position: absolute; z-index: -1; "></div>
        <div id="content" style="height:100%; padding:0; margin:0; " class="Select_Institution">

The Errors:

Error      6      CSS validation: Unexpected ':' character.      C:\DOC\IMAS\Controls\InstitutionSelector.ascx      13      114      http://localhost/IMAS/
Error      7      CSS validation: 'filter' is not a valid CSS property name.      C:\DOC\IMAS\Controls\InstitutionSelector.ascx      13      48      http://localhost/IMAS/
Error      8      CSS validation: 'expression(this.nextSibling.offsetHeight)' is not a valid value for property 'height'.      C:\DOC\IMAS\Controls\InstitutionSelector.ascx      13      172      http://localhost/IMAS/
Error      9      CSS validation: 'expression(this.nextSibling.offsetWidth)' is not a valid value for property 'width'.      C:\DOC\IMAS\Controls\InstitutionSelector.ascx      13      221      http://localhost/IMAS/


Any help is appreciated.

Have you tried to actually run the project? The logic appears to work for me:

It could just be Visual Studio's CSS parser acting squirrely.

Do note:  You'll need to populate your <div> with some text in order to see it; otherwise, you'll need to manually fix the width of the <div>.

You're missing a colon after the first "progid".

Kaufmed,

I see that one and I corrected but getting a red squigly line under the Colon and all of them still.

I believe the error may start on the filter: part.  Not sure.  The entire line I believe has several syntax errors.

Kaufmed,

I do not get the errors now when I convert it from VS2005 to VS2008.  Converting from 2.0 to 3.5 framework, I do not get the errors.
