Unit test suite (build 12.x) is failing in render.test.js, line 171 because test expects the output to include a height when only a width is provided.

Should the test be adjusted?

I am not sure whether I can release this soon. Maybe this weekend!
so I would advice is you want this to be changed, you can try

![](<link here> ':width=100')

Thank you! I don't mind waiting. For now, I'll just point my index.html to my compiled version of docsify.min.js.
Happy to contribute to such a great project!

Also, I can't seem to get the syntax ':width=100' to work. Is it currently supported?

oops...I we dont have support for that. I thought we had support for building dynamic attributes from these markdown syntax.

I guess we can have that, that would solve many similar issues

I think this looks legit to me. Didn't think of this when i did the refactoring

Please, can someone merge this pull request?
I had to change to older version which works fine.

<script src="//unpkg.com/docsify@4.10.2/lib/docsify.js"></script>

[maubuz]

Let me know if there is anything required from my end to complete the merge.
A test is failing with a timeout error but I don't see the connection with this PR.

[maubuz]

I did a rebase on top of latest develop branch. Nothing was changed in the code.
All tests are passing now.
