                If you xxx give up, you will achieve nothing. Practice won’t get you anywhere if you mindlessly xxx practice the same thing. Change only occurs when you work deliberately with purpose toward a goal. Sometimes it is appropriate to place various typographic elements on the outside of the xxx left margin of text to maintain a strong vertical axis. This practice is referred to as exdenting and is most often used with bullets and quotations.

Answer 1

问题是由于 position:fixed。将其更改为 position:relative。

 footer{
        clear: both;
        font-size: 20px;
        bottom:0;
        width:100%;
        text-align: center;
        background-color: rgba(0,  0,  0,  0.7);
        color: white;
        font-family: 'Oxygen';
        position: relative; 
    }
