Montauk Tags Prefix – Custom CSS Change?

Hi –

Using Montauk, I want to add a colon to the Tags prefix after each blog post.

Currently I see the following in the source code:

**<span class="tags-title">Tags</span>**

I would like to change this so that there is a colon after the word Tags, as follows:

**<span class="tags-title">Tags:</span>**

Note the colon after the word Tags.

Is there a workaround in custom CSS to make this change please?

Thanks

Ian
