0HTML5 LogoResponsive lazy backgrounds instead of css background-image

Gepubliceerd door & gearchiveerd onder Web Technologies. Laatst bijgewerkt .

I’ve recently been work­ing on an update/overhaul of both my vari­ous web­sites and the serv­er backend. As part of this pro­cess I’ve been try­ing ot make sure everything is using the latest stand­ards to max­im­ise per­form­ance and com­pat­ab­il­ity. One of the best fea­tures of recent ver­sions of word­press is the nat­ive sup­port for respons­ive images — where the img­set=”” attribut eis used to sup­ply altern­at­ive sizes of images in a group so the browser can use the most appro­pri­ate.

I recently ran into an error with a new nginx con­fig that I could­n’t find any­where on google!

Posted door & gearchiveerd onder Web Technologies.

Since switch­ing from my BT SmartHub to a pfsense router I’ve had a few minor teeth­ing prob­lems. One of which has been the squid proxy ser­vice caus­ing a prob­lem where I can­’t access the BBC web­site with an error. Whilst I did even­tu­ally fix this through a slightly strange meth­od, I encountered a pos­sible source of the prob­lem which was worth fix­ing on it’s own
