You can link to another Thimble page from Thimble. Be sure that you publish the page you will link to so that you have a “shareable” web address for it. Then you can create a link to this page in a second page.
I am using the new version of Thimble.
- I created and published the Postcard.
- Then I edited the Poster to link to the web address for the Postcard.
There are different web addresses for the edit window and for the published page. You can only link to the published page web address.
You can have more than one Thimble edit windows open, so long as they are for different pages. However, if you are new to web development, I recommend that you only work on one page at a time.
