CSS inject from a CSS file referenced in a <link> tag

[OrhanOctavian]

Hi,

Is it possible to inject CSS code from CSS files that are linked in a HTML file through <link> tags (example: <link rel='stylesheet' href='css/main.css'>)?

While adding a <style> tag in the html file works fine and instantly applies the CSS changes to the preview browser window, I am wondering if I could achieve the same with a css file that is linked using a <link> tag. This would be useful because normally the css files are stored separately from the html file, to avoid the clutter of having <style> tags in the html files.
Manually saving the CSS file is effectively updating the preview, but CSS injection would be more useful, particularly when designing the style of elements ( for example using the color wheel to live preview the changes in the browser, contrary to testing one color at a time by hitting save in between).
