As of today (2017/01/21) I’ve noticed that Tumblr descriptions that have HTML integrated in them no longer show up properly. Tumblr now completely ignores and deletes any custom HTML and only shows plain text. One way to fix this problem:
- Go to your Tumblr main page, right-click and view page source. Do this BEFORE you click “Edit Theme”
- Search for your description text in the source page by typing the exact words of your description
- Copy your description text. It should be in between
and. Note that the word “desc” can be anything, it’s just the element name that holds your text
- Go into “Edit HTML” of your Edit Theme page, and replace {Description} with your description text you just copied
All the HTML of your description should now be intact. Note that you will have to repeat this process if you change your theme.
