The certificate of fontastic.me is expired, and cors is invalid. Better to use another approach

I just noticed while browsing through the Hugo theme page of this theme, that the "Homepage" URL is pointing to example.com.
See https://themes.gohugo.io/hugo-webslides/

Seems to be caused by this line in your theme.toml:

im with hugo v0.101.0. I put your _index.md files from exampleSite in content, the css instructions are not read.

If I want to link to a specific slide I need to link to #slide=13

But if I am generating the slides from several markdown files then we don't know the number in advance

Would it be possible to link to a named slide in file2.md when I am editing slides in file1.md and have Hugo calculate where to go to

Otherwise the current slide linking breaks if you have a series of links to do. Alternately could we reference a particular slide in a particular file?

Currently, the class assignment expression is inconsistent between slide properties and block properties.

In slide properties, we use dot to assign class (.class) and the number sign to assign id (#id), two dots creates a div (with class assignment) beneath the slide

Hugo v0.60 changed to the GoldMark Markdown parser. Its not rendering the theme correctly

Added the following to the config.toml file and the site renders correctly now
[markup]
defaultMarkdownHandler = "blackfriday"

Following the Hugo sites recommendation of setting changing the markup configuration for Goldmark to unsafe mode to true if you have lots of inline html did not solve the issue

markup:
goldmark:
renderer:
unsafe: true
