The upcoming WordPress upgrade should work fine with our themes out of box, if there is any issue then we will issue theme update accordingly, so you have no reason to worry
Your custom CSS should remain as it is. But, you should always have your custom CSS backed up.
Some tips before you Upgrade WordPress:
- Don’t upgrade on day 1, in fact wait at least 7-10 days.
- Browse the official forums to check if people are having any issues with the theme and plugins that you are using before upgrade.
- If it is not a WordPress security upgrade, you can wait even longer depending upon how bad you want the latest features.
