Problem with the top position of the sidebar-CodePudding

I need help with this sidebar. It does not want to be placed at the beginning of the top edge. ( It protrudes a few millimeters from the top) It looks like: enter image description here.

CodePudding user response：

I checked your code. You have to add top and bottom

.sidebar_container{
    position: fixed;
    width: 220px;
    height: 100%;
    left: 0;
    bottom: 0;
    top: 0;
    overflow-x: hidden;
    overflow-y: auto;
    background: #303030;
    color: #fff;
}
