Auto-hide promo banners
A script watches the page and hides promo banners that appear dynamically while you work.
Code to copy
try {
var sel = [
'[aria-label*="Upgrade" i]',
'[data-testid*="promo" i]',
'[class*="proPromo" i]'
];
var sweep = function () {
sel.forEach(function (s) {
document.querySelectorAll(s).forEach(function (el) {
if (el && el.style) { el.style.display = 'none'; }
});
});
};
sweep();
var mo = new MutationObserver(function () { sweep(); });
if (document.body) {
mo.observe(document.body, { childList: true, subtree: true });
}
} catch (e) {
console.warn('Canva promo sweep failed:', e);
