I came up with a solution to create a "read more..." function using two div elements, and hiding one of them with display: none. The only downside is that it doubles the data storage. Now, here's my question:
If I have just one div element with style="display:none", containing multiple large images, will this affect the loading time of the page?
display:none doesn't stop the hidden content from loading along with the rest of the page.
To reduce the load time of the page, consider using Ajax to load the "read more.." content only when it is requested.
Even if the parent div is hidden with display: none, the images can still be fetched immediately.
If you don't want this behavior and prefer not to use AJAX, one option is to insert the images into the DOM only when the user clicks on a "read more..." button, like in the code snippet below:
var hiddenContainer = document.getElementById("your-hidden-container-id");
var newImage = document.createElement("img");
newImage.setAttribute("src", "image2.png");
hiddenContainer.appendChild(newImage);
