I have one folder name is "Frontend" and under this folder I have Subfolder name Like: Images CSS JS Font

I want to disallow below folder /forntend/css/ /forntend/js/ /forntend/font/

but I don't want to disallow /forntend/images/ or /forntend/

If I am adding this text on robots.txt it is correct or not Disallow: /forntend/css/, Disallow:/forntend/js/, Disallow: /forntend/font/

Please let me know
