I set in config/application.rb usually config.i18n.fallbacks = [:de, :fr, :en] So you can declare the order of the fallback. But keep attention in some environments/*.rb the configuration is overwritten.
The way I solved this problem, is introducing a pure CSS fall-back, that older browsers that don’t support CSS calc would only read. figure.left { width: 48%; width: -webkit-calc(50% – 20px); width: -moz-calc(50% – 20px); width: calc(50% – 20px); } The left and right panels, get a width of 48% if the browser cannot read … Read more
One way to do it SELECT IFNULL(MIN(`file`), ‘default.webm’) `file` FROM `show`, `schedule` WHERE `channel` = 1 AND `start_time` <= UNIX_TIMESTAMP() AND `start_time` > UNIX_TIMESTAMP()-1800 AND `show`.`id` = `schedule`.`file` ORDER BY `start_time` DESC LIMIT 1 Since you return only one row, you can use an aggregate function, in that case MIN(), that ensures that you’ll get … Read more
A polyfill is a browser fallback, made in JavaScript, that allows functionality you expect to work in modern browsers to work in older browsers, e.g., to support canvas (an HTML5 feature) in older browsers. It’s sort of an HTML5 technique, since it is used in conjunction with HTML5, but it’s not part of HTML5, and … Read more
To confirm that cdn script loaded you can check for existence any variable/function this script defines, if it is undefined – then cdn failed and you need to load local script copy.
