responsive-email is a framework-agnostic set of utility components that allow to build responsive email templates with the best support possible. It does not make use of media queries nor other unsupported ways of doing responsiveness on emails.

npm install @responsive-email/jsx-email

<ResponsiveRow>
  <ResponsiveColumn span={1}>First</ResponsiveColumn>
  <ResponsiveColumn span={2}>Second</ResponsiveColumn>
  <ResponsiveColumn span={1}>Third</ResponsiveColumn>
</ResponsiveRow>

These two components are only meant to be used in unison as shown in the above example.

The <ResponsiveRow> will divide its maxWidth (which is 600 by default) into the amount of columns you pass onto it. It does this by detecting which one of the children are actually an instance of <ResponsiveColumn> based on the fact that all React elements are actually objects under the hood that, if they represent a Function Component instance, have their props exposed and easy to access.

The <ResponsiveColumn> by itself only renders a Fragment as it is meant to only be rendered inside the <ResponsiveRow>. The span property allows the user to increase the size of a certain column so that its width can be the sum of the respective amount of columns specified in span, e.g. span={2} will result into a column that has a width of two columns.

The <ResponsiveRow> will also log a warning if it finds you are using more than three columns, as is best practice to use only three columns on email templates.

Each column will wrap in the same way as flex itself would, this is a behavior is known as "collapsing" can occur. In this context, "collapsing" refers to the behavior where the ResponsiveColumn elements wrap onto a new line within the table, rather than expanding the table's width to accommodate their combined width.
