Can I access local storage from a Chrome extension's options file using CSS? Is it possible to use JavaScript to define a variable that can be utilized in CSS, or is local storage only accessible through JavaScript? If local storage is restricted to JavaScript, are there alternative methods for defining CSS options without utilizing local storage?
localStorage is exclusively accessible through JavaScript. CSS files do not support dynamic queries as they are primarily static (though this has evolved with the introduction of new CSS properties like variables); you still cannot retrieve data that is not directly imported.
The only way to dynamically adjust options in CSS is by modifying the state of the HTML (such as changing class names), or by dynamically adding stylesheet rules via JavaScript, or straightforwardly manipulating styles using JavaScript, for example: element.style.property = 'value'.
