Are elements that display:none loaded?

Question

css

That is, can I reduce the physical size of the page being loaded for mobile devices by simply setting all heavy elements to display none in css via the min-width property?

Answer 1

No. The physical size is the actual size of the HTML, regardless of its CSS settings, however, the rendering speed will increase (if you specify display:none in the head section, preferably inline code) , because there is no need to draw "extra" - a trifle, but nice to the eye!))

Answer 2

setting all heavy elements to display none

Answer 3

Page size = weight of html (rendered page) + scripts + css + images.
If you hide it with display=none, then the content between tags with this style will simply not be displayed, but the weight will not decrease. If there is a picture in it, then it will participate in the "formula" of the first line of the answer.
