If we need to show visitors to our site a custom text message we can rely on different instruments.
We can create an image with the notice and place it on the home page, or write the message as plain text.
A fun and original solution would be to display the alarm within a Post-It, or rather, inside a box identical to the graphic cards famossissimi yellow stick anywhere.
If our site is managed with Joomla we have a free add-in that allows us to achieve this effect in a few minutes.
The module is called Mini Post-it and you can download by referring to this page of the official website.
Once downloaded unzip the file is not compressed, but let's move directly into the administration panel of Joomla voice within the install / uninstall extensions reached from the menu.
We choose, through the browse button, the file extension. Zip and install the module by clicking on the Upload File > After a few seconds a message we will alert the proper installation of add-on.
Moving now activate the module in the module manager in the menu extensions. We identify the item in the list JF Mini Post-it and click on the red circle with white X on his right to activate the component and make it visible.
The installation was completed. At this point we have to do is edit the text and the graphics settings of the text and post it. We click, always from the same list, the item JF Mini Post-it.
On the right side of the browser window has two panels called module parameters and advanced parameters.

If we choose the stylus the graphic effect will be as follows:
