postcss-dynamic-value

PostCSS plugin that implements CSS actual value selectors for inputs.

Standard CSS attribute selectors do not capture the actual (user modified) value attribute for HTML input elements. They, instead, use the static initially set value.

This plugin allows capturing the dynamic value, by using a colon prefixed value attribute selector.

input:[value="test"]
