-## Logo
-
-The `logo` option allows extra customization in Typst for full control over layout.

-In all formats, `logo` can be the path to a logo or the name of a `brand.logo` resource, i.e. `small`, `medium`, or `large`. It can also be an object with

-: Image path or name of `brand.logo` resource

-`width`
-: Width in CSS units. Default `1.5in`.

-`location`
-: Location on the page in X and Y using CSS [`text-align`](https://developer.mozilla.org/en-US/docs/Web/CSS/text-align) and [`text-vertical-align`](https://developer.mozilla.org/en-US/docs/Web/CSS/vertical-align) keyword values, specifically
-`left`, `center`, `right` and `top`, `middle`, and `bottom`.
-  The X and Y components are combined with a dash, e.g. `left-top` (the default), `center-middle`, etc.
-  Applied as Typst [`align`](https://typst.app/docs/reference/layout/align/).

-: Amount of padding to add to each side of the logo, using CSS [`padding`](https://developer.mozilla.org/en-US/docs/Web/CSS/padding) conventions. Due to a limitation in the Lua implementation of YAML, multiple padding options are applied in alphabetical order instead of the order of the YAML object. Applied as Typst [`block.inset`](https://typst.app/docs/reference/layout/block/#parameters-inset). Default `padding: 0.75in`.
