background & & question:
as shown in figure
add: I use
in the less filediv2{
height:calc(100vh - 140px)
} does not work, the view in the browser is calculated as-40vh.
but it"s easy to debug calc (100vh-140px) directly while browsing. What happened during less compilation?
less is written incorrectly. It should be height:calc (~ "100vh-140px") , because less is calculated automatically, and adding ~ symbol prevents it from calculating.
calculation attribute: calc (100%-140px);
absolute positioning method:
div2{
position:absolute;
bottom:0;
top:140px;
left:0;
right:0;
