Show the categories name


When we start arranging blogs in categories we put some name.
But how can we show that categories name to the post specific to it?


On a post, to display the category that post belongs to you would use {{ page.category }}


And how to link it to its category page.


The same way you call it in above. Add that variable to a href.

Just note that Jekyll doesn’t create category pages for you, so just because you use something like <a href="/{{ page.category }}">{{ page.category }}</a> in your layouts doesn’t mean it will resolve.

You’ll need to manually create those archive pages or use a plugin like Jekyll Archives to do it for you.
