在液体中,"w" 和 "x" 的单位是什么?

In liquid, what are the units "w" and "x"?

我正在修改一些 Shopify Liquid 代码,发现以下单位对我来说没有意义:1600x 1600w

我假设 "w" 指的是宽度,但这些是以像素为单位的吗?然后我不知道 "x" 指的是什么。

<img  alt="{{ section.settings.image.alt }}"
          {% if section.settings.image != nil %}
            src="{{ section.settings.image | img_url: '100x' }}"
            data-src="{{ section.settings.image | img_url: '2048x' }}"
            class="lazyload lazyload--fade-in hsContainer__image"
            sizes="100vw"
            srcset="  {{ section.settings.image | img_url: '2048x' }} 2048w,
                      {{ section.settings.image | img_url: '1600x' }} 1600w,
                      {{ section.settings.image | img_url: '1200x' }} 1200w,
                      {{ section.settings.image | img_url: '1000x' }} 1000w,
                      {{ section.settings.image | img_url: '800x' }} 800w,
                      {{ section.settings.image | img_url: '600x' }} 600w,
                      {{ section.settings.image | img_url: '400x' }} 400w"
          {% else %}
            src="{{ 'placeholder.svg' | asset_url }}"
            class="hsContainer__image"
          {% endif %}
           />

"w" 指的是图像的宽度作为 srcset 的参数,如下所述: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img#Example_3_Using_the_srcset_attribute

x 用作分隔宽度和高度参数的字符,如下所述: https://help.shopify.com/en/themes/liquid/filters/url-filters#size-parameters
