Use the {% capture %} tag to assign complex strings to variables
If you want to get a string that’s semi-complicated to construct, you can put a “mini-template” in the {% capture %} tag to build it over multiple lines.
You can use the [capture tag] to create a new variable:
{% capture variable %}
value
{% endcapture %}```
This could be quite useful for building up complex variables with several conditionals or loops, inside the template.
I first saw this variable being used in [an article by Jesse Squires][squires], and although I don't have a use for it right now, it's a useful one to remember.
