The first thing you need is the images for the decoration. Don’t make them too big, because you can’t click on anything below images. Below is a simple example I got from Office Online, merged it, removed background and reduced its size. Make sure you have a transparent image (a .GIF or .PNG with transparent background).

The first step is to upload the image to site’s document or picture library and copy the original image’s URL to clipboard. (don’t copy the SharePoint thumbnail or web preview image, as they tend to get white background instead of original transparent).

Next on your homepage add a Content Editor Webpart into any zone and edit its source.

And in the source simply type the following code:

<img src="[your-coppied-image-url]" style="position:absolute; top: 0px; left: 48%; z-index: 99;" />

After you click "Save" and "Apply" the page in edit mode will have the decoration in a wrong place.

But not to worry, after you exit edit mode, the image will be in the right position. So final result might look something like below:

There are numerous variations. You can change the position, you can even use a div with a repeating background image,…

Merry Christmas and a Happy New Year to all SharePoint users and admins!

P.S. If you have any good image (appropriate for transparent background and not violating any copyright rules) for season’s decoration, please drop me a link in this post’s comments.

When the .js file is uploaded copy its location. Easiest is by right-clicking the document link and selecting “Copy Shortcut”.

Now let’s open the list view of the calendar.

Now we create an additional column for displaying day of the week. The details are described in this post only using the day name. The formula is

=TEXT([DateField],"ddd")

In the example above in locales where you use decimal comma, use the semicolon as parameters separator.

Next add the created column to the view.

Now using the method from this post drag the Content editor webpart to after the list view

Open the webpart’s ToolPane and edit the source code.

First insert the uploaded jquery script (which’s shortcut you’ve coppied to Clipboard)

<script type=”text/javascript” src=”http://[site][/web]/sys/jquery-1.3.2.min.js></script>

in the code above replace the src parameter with the url of the uploaded jquery.

Next add the following code:

<script type=”text/javascript”>
$("table.ms-listviewtable tr:contains(‘Sat’) td, table.ms-listviewtable tr:contains(‘Sun’) td, table.ms-listviewtable tr:contains(‘Sat’) td a, table.ms-listviewtable tr:contains(‘Sun’) td a").attr({ style: "color: red;" });
</script>

The code above will color all the texts and all the llinks in weekends in red. The full code is shown in the screenshot below:

And the result is:

Because this can be a painstaking job, I’ve composed a simple command-line utility to cycle through all of the webs in a site collection and apply default theme and reapply existing theme.

You can download it from CodePlex.

Usage is simple. Download it to the server running Windows SharePoint Services site you wish to reTheme. Open command prompt in the download folder and run command retheme http://site_collection_url.
