System requirements
All the stacks sold through this website require RapidWeaver and the Stacks plugin. They will not install or work with any other publishing platforms (like Flow, Drupal, Blocs or Wordpress).

We recommend you aim towards installing the latest version of RapidWeaver that your computer is capable of running (preferably RapidWeaver 7 or greater) and Stacks 3 or later. Both are a separate purchase if you do not own them already.

Stacks4Stacks generously provides you fully-functioning free demo versions of everything sold on this website. This enables you to fully test addons before committing to a purchase. There are no time or functionality limitations applied.

If you cannot get the free demo version to work, DO NOT proceed with purchasing the stack - because the purchased stack is unlikely to work any better for you. Please request technical assistance first.

License agreement

You may use a purchased stack an unlimited number of times in personal or commercial projects and request technical support.

We permit you to install stacks onto all computers that you own. You are permitted to make private archival backup copies (e.g. iCloud, Disk Blaze, Google Drive or Dropbox).

You may not resell, redistribute or make a stack available for download, remove copyright credits, license information, or claim the stack to be your own creation. This includes free stacks, demo stacks or paid stacks, in modified or unmodified states.

The software is provided "as is" without any implied or expressed warranty of merchantability or fitness for purpose. In no event shall the authors or copyright holders be liable for any claim, damages or other liability, whether in an action of contract, tort or otherwise arising from, out of or in connection with the software or the use or other dealings in the software.

Refund policy
By purchasing from this website, you agree that your purchase will be available immediately via digital download and that you waive your statutory right of withdrawal.

All purchases are final. Refunds cannot be provided (we physically cannot un-download or remove stacks from your computer) under any circumstances.

You are reminded to make use of the free demo versions already provided on the website, to fully evaluate stacks for compatibility and suitability before making a purchase.

If you cannot get the free demo version to work, DO NOT proceed with purchasing the stack - because the purchased stack is unlikely to work any better for you. Please request technical assistance first.

Be certain that the stack you are buying is actually the one you want, and that you don't already own it or are confusing it with another stack of similar name or functionality.

Porthole is the go-to stack element to use, if you're seeking to create highly attractive and eye catching circle effects in your web pages. You can use a single Porthole stack on its own to display an image or blockquote. Porthole stacks are excellent for displaying photographs next to personal profiles. Alternatively you can create a complete grid of Porthole stacks, and build brilliant and innovative navigation structures or image galleries. Using this simple stack, you will find no end of creativity.

Here are some key features of Porthole:
  • Use one or more Porthole stacks on the same page or import Porthole stacks into non-stack page types
  • Support for gorgeous Google-embedded web fonts that make your content shine
  • Two text placeholders per Porthole, for larger and smaller titles
  • Font Awesome icons supported (in RapidWeaver themes advertised as having Font Awesome support)
  • Set Porthole stacks as links to resources, internal pages or external URL's
  • Apply solid colour fills, CSS gradient backgrounds or images backgrounds
  • Lots of useful style, colour and layout settings to make setup easier for you
  • Porthole stacks degrade gracefully in older web browsers (without support for CSS border-radius)
  • Subtle rollover animation effects to create a nice finishing touch


Here is an example of 9 Porthole stacks arranged as a grid:

In this instance, the free UsefulGrid stack was dragged and dropped into the page. Porthole stacks were then dragged and dropped into each grid box. By changing the text and background settings, each Porthole stack is different in appearance and content.

Not just circles! Porthole is also fantastic for square boxes with written content centred and presented within. This makes Porthole ideal for large theme headers and banner containers. In the example below, a warehoused image was used. Rounded corners were set to 0px. The Content Top setting was adjusted to 35%. The font sizing was increased (to 600%) and a different font face (Oswald) was used. The Porthole stack was set as a link to another website.


Getting Porthole stack setup within a page is a relatively easy affair.
  • Once installed, drag and drop a Porthole stack into your page
  • Double-click in the first text box to change the title shown. Its recommended that titles have a total length of just a couple of words
  • Next, double-click in the second text box to change the subtitle shown. Again its recommended that subtitles are kept short
  • Open the stack settings on the right. Change any of the style, colour or layout settings as you see fit.

Hovering your mouse cursor over the Porthole settings will display information tooltips about what each setting does or how it can be configured. You'll notice that things like text sizes use percentage units of measurement, for maximum flexibility. You may need to keep previewing the Porthole stack and tweaking the settings, to get things just right.

Print output

Porthole stacks print in a simplified style, resulting in less ink and paper wastage. Text is printed in black (so it contrasts against white paper). Background fills, gradients and images are removed.


By default, a Porthole stack added to a page will be 100% wide (of the given area) and will extend vertically to the same proportions. Therefore it's recommended (but not essential) that you either constrain the width of Porthole stacks using the existing Fill Mode settings (available to all stack elements) or consider putting Porthole inside a float, grid or column stack. Any of these can be used to reduce the size of your Porthole stack. The examples shown above were nested inside a free UsefulGrid stack, using the default settings.

Browser compatibility

Rounded corners will not be rendered in IE7 or IE8; where Porthole stacks will get rendered as simple square boxes instead (you can see what this will look like by setting the border radius setting to 0px in the stack settings). On all newer web browsers (like IE9, IE10, IE11, Safari, Firefox, Chrome and Opera) Porthole stacks will render almost identically, in comparison with each web browser. Some CSS gradient effects may not get shown in certain browser configurations (and will default to a flat colour instead). Porthole is not really using any top-notch sophisticated technology as such. Most of it is just standard HTML and CSS code.
