How to defer offscreen images in hubspot?
on our datamatics website (https://www.datamatics.com), there is lazy-loading offscreen images, for this problem, we have found one solution through scripting code and attribute change name inside the <img> tag in HTML file. However, if we change attribute name of src to data-src in <img> tag, next time if we want to replace this image with new one, so this attribute name will change automatically to data-src or do we need to update it manually in HTML file?
Is there any other solution for how to defer offscreen images in hubspot?
if yes, then please suggest.
