## Overview After you integrate the components, you may consider modifications such as customizing the user interface by setting attributes, including those that refer to customized `.css` and font files. There are multiple types of interface customizations you can optionally provide for the components to seamlessly blend their appearance into your parent page. Customizations must be explicitly set individually on each component. Apply these customizations using the files provided in: * `assets` folder for the Account Linking component * `as_assets` folder for the Account Summary component The locations of these folders are described in [step 5](https://developers.byallaccounts.morningstar.com/docs/5-install-components). ## Instructions ### 1. Edit the customization files Each customization type below describes the file you edit and the attribute you set on the component to apply it. Terminology — Override the static text (labels, buttons, dialog content) displayed in the components.

File to edit: i18n/en.json (in the assets folder for Account Linking, as\_assets folder for Account Summary)
Attribute to set: translate-file-path
Note: Each component has its own en.json file with a different set of terms.

Styles — Override the default Morningstar Design System (MDS) styles for fonts, colors, and backgrounds.

File to edit: Your custom CSS file
Attribute to set: override-css-file
Note: Each component has its own CSS file. To use a font other than the default MDS font, add a global rule like:

```css * { font-family: YourFont, Verdana, sans-serif !important; } ``` Fonts — Override the default MDS fonts.

File to edit: Your custom font definition file
Attribute to set: custom-fonts
Note: Each component has its own fonts file. Fonts defined here are then available to use in the CSS file specified by override-css-file.

Optional features — Toggle UI sections in the Account Linking component on or off.

File to edit: config/ui-config.json
Attribute to set: ui-config-file

The currently supported options:

fiLogosVisible — controls whether the popular FI logos are shown in the FI selection step. Set to true to show logos, false to show only a search control and FI list.
includeURLinSearch — controls whether FI URLs are included in the search criteria when the user is searching for an institution.

fiLogosVisible: true — popular FI logos shown

### 2. Configure your web server Modify your web server to allow our origin ([www.byallaccounts.net](http://www.byallaccounts.net)) to access the customization files. We suggest the following: * `Header set Access-Control-Allow-Origin "www.byallaccounts.net" ` * `Header set Access-Control-Allow-Headers "Cache-Control,Content-Type,Accept,Referer,User-Agent,Sec-Fetch-Dest" ` * `Header set Access-Control-Allow-Methods "GET,OPTIONS"` If this access is not allowed, the components will not be able to access the customization files and each will use its own default version. ### 3. Set the attribute for each custom file Set the appropriate attribute on each component to point to the corresponding custom file. For attribute information, see [step 6](https://developers.byallaccounts.morningstar.com/docs/6-incorporate-components-into-parent-page). > 📘 Additional Configurability Options > > The options documented here represent the subset of customizations you configure directly via `ui-config.json`. Additional firm-level configurations are available for the components — such as financial institution exclusions, new institution requests, Account Summary default and chart views. Your Implementation Manager will guide you through these choices during the implementation phase.
