I'm seeking help with a persistent issue on my Joomla 5.1.2 website built using Konstra and SP Page Builder. I'm experiencing inconsistent font sizes in mobile devices (tablet/mobiles) throughout my content, where some text appears smaller than 16px (my desired size). I've tried the following to resolve it

• Checked Template Settings: I looked for a "Base Font Size" or "Body Font Size" option in the Helix Ultimate template settings, but couldn't find anything specific.
• Custom CSS: I implemented the following CSS code in the template's custom CSS section, but it didn't seem to have a consistent effect

.sp-body { font-size: 16px; }

Secondly the slider is NOT responsive in mobile view
