    Hi milanparmar22,

    By default the critical CSS input field is a CodeMirror editor with CSS Linter that will start linting as soon as CSS is entered. When entering a large amount of CSS or on a low power device this may cause javascript to crash.

    You can disable the CSS editor using the option Use a CSS editor with error reporting (CSS Lint using CodeMirror). directly below the Critical CSS editor.
