I use the above code to beautify my scroll bar, but I do not want to style my vertical bar.

I tried to remove the tags which don't contain 'horizontal' but it doesn't work.

Answer 1

For horizontal scroll bar set height

    ::-webkit-scrollbar{     width: 12px;     height: 12px;     } 

Answer 2

Once you've set the css for

::-webkit-scrollbar{} 

both the horizontal and vertical bars are automatically affected.

If you want the horizontal bar to look different from the vertical bar, you will have to set separate CSS for each, like this:

::-webkit-scrollbar-thumb:horizontal {     background-color:#5B0B2B; } ::-webkit-scrollbar-thumb:horizontal:hover{     background-color:#B31252;     border: solid 1px #5B0B2B; }  ::-webkit-scrollbar-thumb:vertical {     background-color:#2A8894; } ::-webkit-scrollbar-thumb:vertical:hover {     background-color:#32BFD1;     border: solid 1px #2A8894; }
