# Retroactive CSS/HTML updates since 1.18.3

* Added text-zoom tuning for checkbox checkmarks at 235% zoom: under `html[data-text-zoom="xlarge"]`, `.a-checkbox__holder::before` uses `font-size: 0.8511em` so the checkmark stays visually aligned with 200% zoom behavior; implemented in SCSS file `src/scss/general/components/atoms/_checkbox.scss` on pages that use checkboxes (e.g. styleguide checkbox page, search transaction filters overlay).
* Updated authentication layout: removed `text-align: center` from the authentication container and removed fixed `width: 13rem` from `.m-authentication__input` in SCSS file `src/scss/general/components/molecules/_authentication.scss` on page `styleguides/general/molecules/authentication/authentication-page`.
* Commented out responsive `max-width` breakpoint rules for the default `.l-container` (tablet, desktop, desktop large) so the mobile-based max-width calculation applies across breakpoints; change is in SCSS file `src/scss/general/layout/_container.scss`.
* Adjusted extra-large text zoom grid behavior in SCSS file `src/scss/general/layout/_grid.scss`: under `html[data-text-zoom="xlarge"]`, removed `width: 100% !important` from grid columns and added rules for `.l-grid--normalize-with-margins` so nested `[class*="l-grid__col"]` use `flex`/`max-width` instead of forcing full width.
* Added a commented-out reference block for optional `.l-form__grid` column widths at `xlarge` zoom in SCSS file `src/scss/general/layout/_form.scss`.
* Removed `.p-open-accounts__grid` rules that centered `.m-new-account` with `margin: 0 auto` in SCSS file `src/scss/general/pages/_open-accounts.scss` on open-accounts pages.
