I created a form in a page I called Weebly Form Tester and when it was published for some unknown reason Weebly called the page dev-web.weebly.com/wsite-form-tester.html and not dev-web.weebly.com/wsite-form-tester.html.

When published it produced a  404 error stating page could not be found. I renamed the page RT Form Tester and all OK!

In fact the above will make little sense as again when published it changed the weebly in the second url to wsite.  Strange.
 
I can find no text command to do this but it can be easily achieved by using multiple columns.

A major advantage of multiple columns is that they can be included within a column and the dividing position of the columns can be dragged to any position. These features enable one to embed text as shown in my Test Page.
 
This could not be easier. I develop site on my MacBook and have my iPad on the table beside me. On the iPad I have my Weebly published site open on Safari. Every time I publish amendment or addition from my Mac I just refresh Safari page on my iPad to check all is OK.
