Responsive layout

Hi,
I have tried to add some code in order to have some content from this page https://www.ninserviziogratuito.co.uk/tutte-le-nostre-guide changing.

On the Axaj search red bar write something for example “scheda” and check the results… The results should be centred for the desktop view as per this code
/* Ajax search risultati pagina accentrati */
#top .template-search.content .entry-content-wrapper {
padding-left: 220px;
padding-right: 220px;
text-align: justify;
}

and not applied to smaller than 600px screens for mobile. Unfortunately this code does not work on the mobile…

/* Prova ad inserire nel CSS */
@media only screen and (max-width: 600px) {
#top .template-search.content .entry-content-wrapper {
padding-top: 0px;
padding-right: 0px;
text-align: justify;
}
}

Could you please help?

thanks,
Marco
