Using Relative Page Layout (RPL)

As mentioned above, using Relative Page Layout (which we call RPL) together with working with the CSS Layout button switched on

offers you the benefits of both types of layout.

Using Relative Page Layout will make CSS-positioned items behave like

table-based items (see previous screenshot). For this screenshot, RPL has

been applied to the Site Folder and the three HTML items in the left column

have the Remove from Relative Page Layout Action applied to them.

To use RPL on your Freeway project you should read through the detailed KnowledgeBase article at http://www.softpress.com/kb/

questions/319/ which tells you everything you need to know.

There are, however, a few limitations you need to be aware of. Although RPL is very clever, it can’t calculate every layout—so there are

some things you should try to avoid, and there are some things which can be fixed by using a Freeway Action specifically offered for

such problems. It can sometimes appear that a layout is completely breaking when in reality just one item on the page needs to be fixed

for it all to work exactly as it should.

RPL has been designed to expect items to be completely on top, completely behind or a completely standalone item. However, if there

are items which partly overlap (or partly underlap) one or more items, RPL may have problems knowing what exactly you want it to do.

This is when RPL needs a helping hand.

Usually there are three options to fix RPL problems—moving an item slightly so it doesn’t partially overlap (or underlap) one or more

other items on the page; selecting the item which RPL is having difficulty with, then applying the Remove from Relative Page Layout

Action to it; and sometimes selecting two or more items (especially if they are overlapping/underlapping) and grouping them so they

are treated as a single item. This is covered in detail in the KnowledgeBase article on troubleshooting RPL problems at http://www.

softpress.com/kb/questions/287/.

In the troubleshooting article mentioned above, you will also get help with any error messages you might see when working with RPL.

The most common error message is shown when an item is not a layer item. For RPL to do its work on the page, every single item on

the page must be a layer item.

Inflow layout

FW Pro only

Inflow layout (often called “inline CSS layout”) offers the web designer all the functionality you need. Building sites which are “fluid”

(ie, sites which are based on percentage widths, so the width of items will change according to the size of the browser window) and

sites which use full-width header and footer bars can only be built when using inflow layout even when the page width itself is a fixed

width.

In the next section the ways to build percentage-based and fixed-width inflow layouts will be explained. Inflow layout is more complex

than the layout methods which have been covered earlier—and you will need to understand the different height and width attributes

involved to make the layout work reliably.

It is very important to plan ahead so you consider which layout method you need to use to achieve the site layout that you require—

because changing your mind later in the project will usually require you to start the site again from scratch.
