I’ve actually changed the password, as I’ve kind of given up. The website is live and has been handed over to the client. W3schools doesn’t seem to care about this particular issue, and if you cange the header tags, the text will render strangely, as I have custom css in place affecting the .slider-cap h2 and h4 classes, and as we have put a full stop/period at the end of the first ‘slide title’, I have instructed the second ‘slide-title to have {text-transform: none;}. I don’t really want my client to see oddness on his new website, so I’ll just have to cross fingers and hope that this doesn’t matter.
I tried editing the tags in header.php which worked, then editing the css accordingly AND changing the settings in the Theme options, but I couldn’t seem to get it to work. If you could instruct me on how to make the appropriate edits, I could do it out of business hours, ensuring that the correct styling is in place.
