Steps To Reproduce

  • Create user.vaultwarden.scss.hbs under data/templates/scss
  • Mount custom logo into /web-vault/images/custom/custom-logo.png
  • Insert CSS from Customize Vaultwarden CSS

compose.yaml

services:
  vaultwarden:
    image: vaultwarden/server:latest
    container_name: vaultwarden
    restart: unless-stopped
    environment:
      - DOMAIN=https://localhost
      - ADMIN_TOKEN=Vy2VyYTTsKPv8W5aEOWUbB/Bt3DEKePbHmI4m9VcemUMS2rEviDowNAFqYi1xjmp
      - SIGNUPS_VERIFY=false
      - ROCKET_PORT=443
      - ROCKET_TLS={certs="/data/certificate.pem",key="/data/private_key.pem"}
    volumes:
      - "./vw-data/:/data/"
      - "./images/custom/:/web-vault/images/custom/:ro"
    ports:
      - 443:443

/data/templates/scss/user.vaultwarden.scss.hbs

/* Use a custom top left logo on login and locked screen page */
auth-anon-layout > main > div > a > bit-icon > svg {
  display: none !important;
}
auth-anon-layout > main > div > a > bit-icon::before {
  display: block;
  content: "" !important;
  width: 175px !important;
  height: 36px !important;
  background-image: url(../images/custom/custom-logo.png) !important;
  background-repeat: no-repeat !important;
  background-size: contain;
}

Expected Result

Logos gets replaced correctly.

Actual Result

Customize Vaultwarden CSS seems to be not working as expected anymore with current version.

Was trying to replace the logo on the login page with the custom css provided - the logo is shown for a brief time and gets again replaced by the Vaultwarden logo - see screenshot/video 1.

/* Use a custom login logo */
app-root img.new-logo-themed {
	content: url(../images/custom/custom-logo.png) !important;
}

With only second CSS the Vaultwarden logo is shown and then replaced by the custom logo (kind of success) - see screenshot/video 2.

/* Use a custom top left logo on login and locked screen page */
auth-anon-layout > main > div > a > bit-icon > svg {
  display: none !important;
}
auth-anon-layout > main > div > a > bit-icon::before {
  display: block;
  content: "" !important;
  width: 175px !important;
  height: 36px !important;
  background-image: url(../images/custom/custom-logo.png) !important;
  background-repeat: no-repeat !important;
  background-size: contain;
}

Using both in combination displays the custom logo first big and then small - see screenshot/video 3.

The custom css is loaded correctly, docker container is restartet and browser cache cleared after every try.
