TIL: Use the {% raw %} tag to describe Liquid in Liquid
If you’re trying to write about using Liquid tags in a Liquid-based site, wrapping your tags in the {% raw %} tag will prevent them being rendered.
This is a problem I had when trying to write my TIL about the {% capture %} tag. I’d written an example in my Markdown source code:
You can use the [capture tag] to create a new variable:
```liquid
{% capture variable %}
value
{% endcapture %}
```but the rendered <pre> block was empty – Liquid ran before the Markdown processor, so it had captured the variable and left empty space.
I found an answer by Marcel Jackwerth on Stack Overflow that suggests using the {% raw %} tag, which in this case became:
You can use the [capture tag] to create a new variable:
```liquid
{% raw %}{% capture variable %}
value
{% endcapture %}{% endraw %}
```(Trying to write a TIL about the {% raw %} is even more of a mess of raw tags and percent-encoding to get the right output from Liquid.)
