How to minimize DOM size and CSS bloat in Page Builders (GHL/WP) for C

Hi everyone,

I've been working on optimizing high-conversion funnel templates, specifically within platforms like GoHighLevel and WordPress. One recurring challenge I face is the excessive DOM depth created by nested sections and rows in these drag-and-drop builders.

At Funnelsflex, our core philosophy is 'Zero-Bloat' design, but we often hit a wall where the platform's native code adds unnecessary weight, hurting the 'Largest Contentful Paint' (LCP) and 'Cumulative Layout Shift' (CLS) scores.

My questions for the experts here are:

Are there any specific scripts or methods you use to 'de-bloat' the header of these page builders without breaking the visual editor?
How are you handling asset prioritization (critical CSS) when the platform doesn't give you full root access?

I'm trying to push the boundaries of technical performance in funnels, and I'd love to hear how other developers are tackling 'Builder Bloat'.

Thanks!

Hello !
You usually should not try to clean the generated DOM with JS after render. It can break the builder and may make LCP worse because the browser still downloads and parses the bloated HTML first.
Try to use fewer nested sections,rows,columns, reusable global sections, simpler layouts and avoid stacking wrappers just for spacing.
You can also remove unused tracking scripts, fonts, animations, sliders, icon libraries and 3rd party widgets and load only what is needed on that page.
Add defer/async where possible for chat widgets, analytics, pixels, calendars, forms...
Check also the critical CSS and improve the CLS.
