Hi Shah,
I see that you are using the Avada theme – Avada adds its own styling for events pages, and I believe the semi-transparent title over the featured image is the intended behavior. I took a look at the event you linked to, and I see how this is an issue for your site.
I would first recommend taking a look at this article, which reviews some of the options for changing the events styles within Avada. You can also try adjusting the “Default stylesheet used for events templates” and “Events template” settings under Events > Settings > Display. These affect how much events pages inherit their styling from the theme.
If this doesn’t make a difference, then you will need to add some CSS (this will be the same for the font sizes as well). We are limited in the amount of support that we can provide for customizations like this, but if you get stuck or have any questions, please let me know – I’ll be happy to point you in the right direction!
Thanks,
Jennifer
