Hide column header in a SharePoint list web part

To remove these annoying headers I used a simple content editor web part. Open up the Source editor and enter the following three lines:
.ms-viewheadertr { display: none;}
Under Layout in the Content Editor Web Part check the “Hidden” check box so you’re web part wont’ be seen on your site and click OK.  The column headers will now be hidden from view.

This method can also be used to hide and/or change the look of other aspects of your SharePoint site without using SharePoint Designer or making any custom modifications.
