重置范围顶部的 padding、margin 和 box-sizing -

*{
    padding: 0;
    margin: 0;
    box-sizing: border-box;
}


#sidebar {
    box-sizing: border-box;
    display: flex;
    position: fixed;
    justify-content: space-around;
    flex-direction: column;
    overflow-y: scroll;
    left: 0;
    bottom: 0;
    background: blueviolet;
    height: 92%;
    width: 17%;
    margin: 0 auto;
    padding-left: 10px;
}

.side, .subs {
    padding: 5px;
    margin-left: 5px;
}

#things, #others, #subscriptions {
    box-sizing: border-box;
    display: flex;
    flex-direction: column;
    padding-bottom: 10px;
}

#things div, #others div, #subscriptions div {
    display: flex;
    flex-direction: row;
    justify-content: flex-start;
    align-items: center;
}

#things div i, #others div i, #subscriptions div i {
    margin-right: 20px;
}
