Ask HN: Why are some webpages sending double content?

1 points by mobiuscog 10y ago ↗ HN

I've noticed recently that some sites (for example: https://www.aerofs.com/blog/) seem to duplicate the content on the page.

The formatting makes the rendered page only show it once, but with some elements (cookies, Javascript) disabled, or just by viewing the source, it can be seen that the content appears twice.

Is this the results of a certain content managament system, or a particular framework ?

I can't imagine that sending double the content is particularly beneficial.

Looking at the page source for that site, they are using Bootstrap as their CSS framework. While not the most optimal way to do things, one set of content is for devices with screen sizes over 768px and the other set is for devices with screen sizes under 768px.
