Hide website-only elements
Cookie banners, store badges, newsletter pop-ups, desktop navigation, the "Edit with …" builder badge. One CSS rule each in custom.css.
Typical app-only changes
App-like layout
Bigger tap targets, safe-area padding for fixed bars, a bottom navigation (or WebViewGold's native navigation footer), hidden page titles that the app bar already shows.
Behavior changes
Rewrite external links to open in the in-app browser, call successhaptic:// after form submits, hide the web checkout for digital goods and show the IAP button instead.
Prompt for Base44
Paste this into Base44 to implement the web-app side. Review the result, publish, then test inside the WebViewGold app.
Prompt to paste into Base44
Make this app look and behave like a native app when it runs inside our mobile wrapper (detected by navigator.userAgent containing "WebViewGold"). 1) Add a helper isNativeApp() and use it to hide the marketing top bar, footer links, cookie notice and any "Made with" element; give those elements the class web-only as well. 2) On screens narrower than 768px, replace the sidebar navigation in the layout with a fixed bottom tab bar showing the four main pages with icons and labels, padding-bottom set to env(safe-area-inset-bottom), and add bottom padding to page content so nothing is covered. 3) Keep the desktop layout unchanged for browser users. 4) Make page transitions instant, without full reloads.
With a good optimized version of your web app you can have a stunning mobile app within a couple of minutes. Additionally to that the customer service is very nice and very helpful! I can just recommend WebViewGold :-)
Two ways to do it for a Base44 app
Pick the one that matches how you work.
Option A: custom.css / custom.js in WebViewGold
Edit the two files in the Xcode and Android Studio projects (or the Cloud Builder fields). They are injected into every page. No deploy of your web app needed; a new app build ships the change.
Option B: detect the app in Base44
Set a custom user agent in Config.swift / Config.java (for example append "WebViewGold"), then add a body class in your web app when it is detected and style
.in-appvariants in your normal stylesheet. Changes ship with every publish, no app update.Combine both
Use the user-agent class for things that change often (navigation, promotions) and custom.css for one-time clean-ups of elements you cannot easily change in the builder.
Verify in review conditions
Open the app on an iPhone and an Android phone, in portrait and landscape, and on an iPad: no desktop header, no horizontal scroll, nothing under the notch.
Starter custom.css
Adjust the selectors to your Base44 markup:
css
/* website-only elements */
#cookie-banner, .newsletter-popup, .app-store-badges, #lovable-badge, a[href*="lovable.dev"] { display: none !important; }
/* desktop navigation and footer links */
header .desktop-nav, footer .link-columns { display: none !important; }
/* safe area for fixed bars */
.bottom-bar { padding-bottom: env(safe-area-inset-bottom); }
/* comfortable tap targets */
button, .btn, a.nav-item { min-height: 44px; }Frequently asked questions
Does custom CSS change my website?
No. It is injected only inside the app. Visitors in Safari or Chrome see the site as before.
Can I inject JavaScript libraries?
Yes, custom.js runs on every page load inside the app. Keep it small and defensive: pages of your Base44 app may load before or after your script depending on the framework.
Do I need a new store version for CSS changes?
For changes in custom.css, yes (it ships with the app). If you want instant changes, use the user-agent detection in your web app instead.
