You can use id attributes suffixed by # within your HTML template code in order to generate
:#id# selectors that you can later use within Enlive template.
For example, if you say:
You can later reference it with
:#content-main# selector, which will be automatically generated for you.
One of the hidden benefist is that if your application code relies on some element in HTML, here it will be validated, and if there's anything referenced that's not present in HTML, you'll get a warning during compilation.
Such ids are automatically removed so duplicate ids won't show up in the output.
