Hardly... When it comes to cascading style sheets.
This can be done, for example, by running a PHP script from the CLI (i.e. from the command line, so that it does not interrupt after 30 seconds, as it usually happens). This script starts an infinite loop, in which it will check how much time has already passed and raise accordingly. ads/posts up.
Or, at each request, before displaying these same ads, check the time and if the hour N has come - raise the corresponding. up ad.
