Hi @samuelkong 

I see the same escaping method is used now 3 times. Here and thanks to https://github.com/samuelkong/liferay-portal/pull/480 twice in https://github.com/topolik/liferay-portal/blob/5282eae2c752e00b070523f530b0cc5d389d5e02/portal-web/docroot/html/common/themes/portlet_css.jspf

Do you think it's worth to create new escapeCSS/sanitizeCSS method?

Thanks.
