Customize With CSS

Learn how to use predefined CSS variables and parts to fully customize the Passage Element UI.

As of passage-elements version 1.11.0, some CSS variables have changed. You may be required to update any previously targeted CSS variables. Learn more in the migration guide

Styling with predefined CSS variables

The UI for any Passage Element can be customized using CSS variables to modify the default configuration of the Passage Element. To use one or more CSS variables, you can add the variable declarations inside of a style block that will be loaded on the page. You may choose to scope the CSS variables in one of two ways:

/* Apply rules to individual elements */
passage-auth {
    --passage-container-max-width: 250px;
    /* ... more variables ... */
}
 
passage-profile {
    --passage-container-max-width: 400px;
}
 
/* Globally apply rules to all passage elements (auth, login, register, and profile) */
:root {
    --passage-container-background-color: #fffff;
    /* ... more variables ... */
}

Available CSS variables for customization

This is the full set of variables that can be used to customize elements. They will apply to and overwrite values for both themes that the element supports by default. Learn how to target customizations to one theme.

Advanced styling with CSS parts

Deeper customization that goes beyond simple styling allowed by the CSS variables is possible using CSS part selectors. Using the CSS ::part() selectors allows for deep CSS customization of the text fields and buttons in the elements, including many common pseudo-classes.

passage-auth::part(input) {
    border-color: #dbdbdb;
}
passage-auth::part(input):focus {
    border-color: #000000;
}

passage-auth::part(button) {
    border: 1px solid transparent;
}
passage-auth::part(button):hover {
    border: 1px solid blue;
}

Styling the profile table

The <passage-profile> and <passage-passkey-table> elements contain a table that can be deeply styled using CSS parts. The full list of supported parts are:

::part(passage-table) // the root <table> element
::part(passage-table-header-row) // <tr> for header row
::part(passage-table-header-cell) // <th> for header row
::part(passage-table-row) // <tr>
::part(passage-table-cell) // <td>
::part(passage-table-expansion-row) // <tr> for expanded row
::part(paginator-button) // the <div> element for each button in the paginator
