Weird flickering effect with HTML/CSS

Just found out that when using in-page popups, using this CSS breaks the page so that it starts flickering/strobing constantly sometimes :D

html {overflow: auto;}

So word of advice: don't use it :) Or use it with some other parameter than "auto".

Hide the Ribbon row in Sharepoint 2010-2013 modal box / dialog popup

Insert the following 3 lines of CSS code into your page:

.ms-dialog #s4-ribbonrow { 
    display: none;
}

Done!

How to display Sharepoint List item/link in a pop-up/pop-in dialog window

Ever wondered why List items won't open in a dialog even though you have enabled "Launch forms in a dialog?" setting of the List?
Well wonder no more, and just create the popup yourself! Use this code:

<a href="javascript:OpenPopUpPage('http://mysite/Lists/Announcements/DispForm.aspx?ID={@ID}')"  >
<xsl:value-of select="substring(@Title, 1, 27)" />...</a>

btw, the code includes trimming text to 27 characters and inserting "..." in the end. Works!
