我对 HTML 和 CSS 真的很陌生，尽管我已经尽我最大的努力来处理这段代码并试图在线（包括这个网站）寻找答案，但都无济于事。所以这是我与这些部分相关的代码：
#logo {
display: inline-block;
margin: -30px 0px -100px 10px;
}
.hheader {

如果任何善良的成员具有所需的知识和能力来帮助我，请输入适合初学者的回复。
这是代码的 JSFiddle：https ://jsfiddle.net/7hb9bd58/2/
该.hhheader高度没有改变，因为，在保证金#logo不影响头大小（这取决于标志的大小），你只移动了#logo，仅此而已。
有没有理由不设置.hheader元素的高度。就像是
height: 190px;
https://jsfiddle.net/7hb9bd58/4/
或者，如果由于某种原因不允许您这样做，也许您可以缩放徽标，并且它似乎会溢出标题容器
#logo {
display:inline-block;
transform: scale(1.3);
margin-left:50px;
}
