Buttons
The plugin has a number of buttons that are not using the standard bootstrap color scheme. The deploy button is using the class btn-warning - which could be fine - but the yellow color added and the text color does not need to be specified. See other buttons in the Remix deploy & run, Solidity compiler, or debugger. (don't use the zksync plugin as the basis for your css development - it also needs updating). To see a few colors buttons, compile and deploy a contract in the default workspace and in Deploy & Run when in the deployed instance there will be a few different button colors:

We will have a style guide for plugins soon. But in the mean time, please update these buttons to the standard Remix colors.
Thanks
