Welcome to TalkGraphics Liliana

You have posted in the Webstyle forum. Are you using WebStyle or Web Designer?

You add widgets to Web Designer and Designer Pro using a placeholder.

Usually the widget will make some code or script that has to be inserted into the HEAD and/or BODY section of the HTML document.

A placeholder can be any object, usually a rectangle that you add the script or code to via Website Properties > Placeholder > HEAD or BODY.

When you preview or publish your page or site, the placeholder automatically inserts the script or code into the HTML document.

Does this make sense?
