Hi there, apologies if this is in the wrong spot. I recently viewed my site and discovered that the margins have since been changed. Going into the site styles everything points towards being correct - Screenshot attached (1st one) – However when i load the website it goes awry and increase padding occurs - Screenshot attached (2nd one). I've played around to try get back to my desired margins where the content is close to the edge but not flush. However it keeps reverting back to having additional margins.
