html - 在我的 CSS 中，我在以“h1 {font-size: 2em;...}”开头的代码底部出现解析错误

Question

以"h1 {font-size: 2em; padding-top: 0.25em; padding-left: 1.5em; width: 85%; text-align: center;}"接近代码结尾的代码开始提供解析问题。我不确定这是为什么。

body {background-color: #3F2860; color:#3F2860; font-family: Arial; }
header {background-image: url(lilyheader.jpg); background-color: #9BC1C2;

padding:1em; border: 3px #CCCCCC;}
nav a {text-decoration: none; display: block; font-weight: bold; text-align: center;
 border: 3px outset #CCCCCC; padding: 1em; margin-bottom: 1em; }
nav ul { padding-left: 0; list-style: none;}
nav a {text-decoration: none;}
nav a:link { color: #3F2860; }
nav a:visited { color: #497777; }
nav a:hover { color: #A26100; border: 3px inset #333333}
main {padding-left: 2em; padding-right: 2em; margin-left: 170px;
 padding-top: 1em}
footer {background-color: #9BC1C2; font-size: 0.60em;
 text-align: center; font-style: italic; padding:1em}
#wrapper {margin-left: auto; margin-right: auto; width: 80%; 
background-color:#F5F5F5; min-width:1200px; max-width:1480px;}
*{box-sizing: border-box;}
.floatleft {float: left; margin-right: 4em}
.clear {clear: both;}
header, nav, main, footer { display: block; }
#mobile { display: none;}
#desktop { display: inline;}
/*big screen 1024 pixel screen*/
@media only screen and (max-width: 1024px){}
body { margin: 0; padding: 0 }
#wrapper { width: 100%; min-width: 0; margin: 0; padding: 0;}

在包含代码的媒体查询之后，您的代码缺少大括号h1。这是修改后的代码：

@media only all and (max-width: 768px) {
    h1 {
        font-size: 2em;
        padding-top: 0.25em;
        padding-left: 1.5em;
        width: 85%;
        text-align: center;
    }
}

您也可以只复制整个内容：

body {
    background-color: #3F2860;
    color: #3F2860;
    font-family: Arial;
}

header {
    background-image: url(lilyheader.jpg);
    background-color: #9BC1C2;
    background-position: right;
    background-repeat: no-repeat;
    height: 150px;
    width: 1600px;
    padding-right: 1em;
    padding-left: 1em;
    /*text-align: center;*/
}

h1 {
    padding-top: 50px;
    padding-left: 2em
}

nav {
    float: left;
    width: 160px;
    font-weight: bold;
    padding: 1em;

}

nav a {
    text-decoration: none;
    display: block;
    font-weight: bold;
    text-align: center;
    border: 3px outset #CCCCCC;
    padding: 1em;
    margin-bottom: 1em;
