## Configuring EVM Chains * **CSS:** Update the import instruction in `apps/block_scout_web/assets/css/theme/_variables.scss` to select a preset css file. This is reflected in the `production-${chain}` branch for each instance. For example, in the `production-xdai` branch, comment out `@import "neutral_variables` and uncomment `@import "dai-variables"`. * **ENV:** Update the [environment variables](env-variables.md) to match the chain specs. ### Current css presets ``` bash @import "theme/base_variables"; @import "neutral_variables"; // @import "dai_variables"; // @import "ethereum_classic_variables"; // @import "ethereum_variables"; // @import "ether1_variables"; // @import "expanse_variables"; // @import "gochain_variables"; // @import "goerli_variables"; // @import "kovan_variables"; // @import "lukso_variables"; // @import "musicoin_variables"; // @import "pirl_variables"; // @import "poa_variables"; // @import "posdao_variables"; // @import "rinkeby_variables"; // @import "ropsten_variables"; // @import "social_variables"; // @import "sokol_variables"; // @import "tobalaba_variables"; // @import "tomochain_variables"; // @import "rsk_variables"; ```
