Ignored powerful shortcuts of jQuery

Many developers ignore shortcuts and power of jQuery and I myself being a victim of some of the useful, handy but yet ignored shortcuts of jQuery. These are not some advance or complex shortcuts but I guess these are used a lot.

Consider, below jQuery code lines.

$("#elm").css("display", "none"); //Line 1
$("#elm").css("display", ""); //Line 2
$("#elm").html(""); //Line 3

Above code lines are very common but its unfortunate because some faster and more readable shortcuts available, yet ignored. Find below jQuery code lines that does the exactly same thing but these are more readable and fast.

$("#elm").hide(); //Line 1
$("#elm").show(); //Line 2
$("#elm").empty(); //Line 3

Another example is of setting height and width,

$("#elm").height(100); //Line 1
$("#elm").width(100); //Line 2

Another common situation is of toggling (show/hide) of element. For example,

    $("#elm").css("display", "none");
    $("#elm").css("display", "");

where the better approach is,
