< less than
>= greater than or equal to

and condition A and condition B

For example:

{% if customer.has_account ==Block Pants EQT Pants Track Block EQT Track true %}
  Welcome back to our store!
{% endif %}

{% if product.type == "Shirt" or product.type == "Shoes" %}
  This is a shirt or a shoe.
{% endif %}


contains checks for the presence of a substring in a string.

{% endif %}

contains can also check for the presence of a string in an array of strings.

Pants Pants Block EQT Block EQT Track Track Order of operations

In tags with more than one and or or operator, operators are checked in order from right to left. You cannot change the order of operations using parentheses — parentheses are invalid characters in Liquid and will prevent your tags from working.

{% if true or false Block Block Pants Pants EQT EQT Track Track and false %}
  This evaluates to true, since the 'and' condition is checked first.
{% endif %}
{% if true andPants EQT Track EQT Track Block Pants Block false and false or true %}
  This evaluates to false, since the tags are checked like this:

  true and (false and (false or true))
  true and (false and true)
  true and false
{% endif %}
