How to Make Our Website to be Ready for IE8

Today, I have email from Microsoft TechNet Flash about "how to get ready for IE8". It is challenge for me to make my blog ready for IE8. My blog have already XHTML 1.0 Transitional and CSS 2.1 compliance, but still reported as not ready for IE8 (see picture below).


What happen with my blog? IE8 have difference standard with W3C? After following link from TechNet flash email, the problem is: my blog have not META tag to tell IE8 that the page is ready for IE8 view. After apply X-UA-Compatible META tag in my BlogEngine theme, my blog is now comply with IE8.


Here’s requirement to be ready for IE8.

  1. Make sure your HTML markup is comply to HTML 4, XHTML 1.0 or XHTML 1.1 defined in doctype of the page. You can validate your page with online markup validation tools at http://validator.w3.org/
  2. Make sure your CSS is use at least CSS level 2.1 compliance. You can validate your page with online CSS validation tools at http://jigsaw.w3.org/css-validator/
  3. Place the following HTML META tag into the top of the HEAD element of each Web page (before tags other than TITLE or META):
    <meta http-equiv="X-UA-Compatible" content="IE=8"/>
    This will tell Windows Internet Explorer 8 to render each page using CSS 2.1 standards.

After HTML, CSS and HTML META has been applied, the page will ready for IE8.

How To Create Silverlight Avatar for INDC blogs site

I have created Silverlight avatar for Community Server blog list page (http://geeks.netindonesia.net/blogs) a week ago as requested by Naren. I think its no difficult to replace HTML avatar with Silverlight avatar on the fly. Just query DOM using jQuery for existing avatar, grab photo Url information, hide it and replace with new Silverlight avatar. Here is step by step to create Silverlight avatar for CS theme on geeks site.

Create Silverlight project using Expression Blend.

I'm created two path to put avatar image and two StackPanel contain text-boxes for view counter text. Second path and StackPanel will mirrored-down to make shadow-mirror effect. These path will be binded by same image.


Here is the XAML for that design.

    Width="133" Height="130">
    <Grid x:Name="LayoutRoot" Clip="M0,0 L133,0 L133,130 L0,130 z">
            <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                <GradientStop Color="#FF8FC2E4"/>
                <GradientStop Color="#FFFFFFFF" Offset="1"/>
            <Canvas Margin="48 1 1 10" >
                <Path Data="M0,0 L82,0 L82,102 L0,91 z" Stretch="Fill" Stroke="#CCFFFFFF" >
                        <ImageBrush x:Name="Photo" />
                <Path Canvas.Top="193.5" Data="M1.5,12 L81,0 L81.75,73.5 L0.25,82.5 z" Stretch="Fill" Stroke="#CCFFFFFF" RenderTransformOrigin="0,0" Height="102.188" Width="82.5" Canvas.Left="0.125" >
                        <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.4,0">
                            <GradientStop Color="#AAFFFFFF" Offset="1"/>
                            <GradientStop Color="#00FFFFFF" Offset="0"/>
                        <ImageBrush x:Name="PhotoShadow" />
                            <ScaleTransform ScaleY="-1"/>
                            <TranslateTransform X="0" Y="0"/>
            <Canvas Margin="2,0,0,0">

                <StackPanel Canvas.Top="48" RenderTransformOrigin="0.5,0.5">
                            <SkewTransform AngleY="6.972"/>
                            <TranslateTransform Y="4.006"/>
                    <TextBlock x:Name="ViewCount" Text="9999" TextWrapping="Wrap" FontFamily="Arial" FontSize="20" Foreground="#FF023D9E" HorizontalAlignment="Right"/>
                    <TextBlock Text="Views" TextWrapping="Wrap" FontFamily="Arial" FontSize="16" Foreground="#FF023D9E" HorizontalAlignment="Right"/>
                <StackPanel Canvas.Top="84" RenderTransformOrigin="0.5,0.5">
                        <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                            <GradientStop Color="#00FFFFFF"/>
                            <GradientStop Color="#AAFFFFFF" Offset="1"/>
                            <ScaleTransform ScaleY="-1"/>
                            <SkewTransform AngleY="7.585"/>
                            <TranslateTransform Y="3.288"/>
                    <TextBlock x:Name="ViewCountShadow" Text="9999" TextWrapping="Wrap" FontFamily="Arial" FontSize="20" Foreground="#FF023D9E" HorizontalAlignment="Right"/>
                    <TextBlock Text="Views" TextWrapping="Wrap" FontFamily="Arial" FontSize="16" Foreground="#FF023D9E" HorizontalAlignment="Right"/>

Write code-behind to bind avatar image and view counter.

This code-behind used to bind avatar image and view counter. The image url and view counter passed by InitParams property from javascript. The App.xaml.cs code-behind used to get InitParams and Page.xaml.cs used to bind the image and text from parameter values.

Note: You must get absolute Url for downloading photo with query string, see line 21-25 above. Silverlight will ignored query string if you are not provide absolute url for image source.


Grab DOM using jQuery

jQyery is very powerful tool for DOM manipulation. You can query and modify DOM with single line of code. Before query the DOM, you should be knows the DOM structure of page. Target of DOM is the avatar image. Open IE development toolbar to get the DOM of avatar. Find ID or CSS classes that used by Avatar to be replaced by Silverlight avatar.


From this information you can analyze that every blog entry placed inside DIV element with content_main_con_be CSS class. This DIV element contain view count and avatar image DIV in first and second child element. Based on this information, you can query the DOM using jQuery as script in line number 11 and 12 below.

 1 /*
 2     Filename: avatar.js
 3     Project : INDC Geeks
 4     Ver.    : 1.0
 5     Date    : March, 4th 2009
 6     Author  : Ahmad Masykur - www.masykur.web.id
 7 */
 9 $(document).ready(function() {
10     if (Silverlight.isInstalled('2.0')) {
11         var viewCountElements = $("div.content_main_con_be div:nth-child(1) > span:even");
12         var pictureBoxes = $("div.content_main_con_be div:nth-child(2)")
13         pictureBoxes.each(function(i, element) {
14             $(element).width(132).height(130);
15             var imageSourceUrl = $('img', element).attr('src');
16             createSilverlight(element, imageSourceUrl, $(viewCountElements[i]).text());
17         });
18         $("div.content_main_con_be div:nth-child(1)").hide();
19     }
20 });
22 function createSilverlight(host, imageSourceUrl, viewCount) {
23     Silverlight.createObject(
24         '/ClientBin/Avatar.xap?v=0.2',
25         host, host +"_Plugin",
26         {
27             width: "100%", height: "100%",
28             background: "#E8CFB0", 
29             version: "2.0.31005.0" 
30         },
31         { onLoad: null },
32         'ImageSourceUrl=' + imageSourceUrl + ', ViewCount=' + viewCount);
33 }

Description of script above are.

  • The script above will be execute when DOM is ready (evaluated in line 9).
  • Line 10 will verify if Silverlight 2 is installed in the machine. If Silverlight 2 is installed, DOM will be replaced with Silverlight object.
  • Line 11 and 12 is getting view counter and picture box elements.
  • Line 13: Make a loop the selected DOM. 
  • Line 14: Set the width and height of element that will be used for Silverlight host
  • Line 15: Get image Url information from IMG element
  • Line 16: Create Silvelight object using javascript.
  • Line 22-33 is function to create Silverlight object.
  • Line 32: Set InitParams value to be passing to Silverlight application.

This script required Silverlight.js and jQuery 1.3.2. The last steps are upload xap file of Silverlight application and required scripts also included the script above, Silverlight.js and jquery-1.3.2.min.js into blog.master of theme.

<script src="/JavaScripts/Silverlight.js" type="text/javascript"></script> 
<script src="/JavaScripts/jquery-1.3.2.min.js" type="text/javascript"></script>
<script src="/JavaScripts/avatar.js" type="text/javascript"></script>

Finally, the geeks portal have a new theme with Silverlight avatar. This avatar will available both installed Silverlight plung-ins or not. User will see HTML version of avatar if they don't have Silverlight plug-ins installed on the machine.


I would like to say thank you to Wely and Naren that support me to make it running well in geeks portal.
