我正在做私有(private)元素，我不知道如何为页面的整个宽度设置文章的背景颜色，而不仅仅是文本周围，就像在 screen1 中那样。
.logo
{
text-align: center;
font-size: 40px;
margin-top: 40px;
margin-bottom: 30px;
letter-spacing: 5px;
text-transform: uppercase;
color: #ddd;
font-weight: 700px;
}
nav
{
background-color: #1c74b2;
text-align: center;
width: 100%;
}
body
{
background-color: #2F3336;
color: #efefef;
}
.menu
{
padding-top: 13px;
padding-bottom: 13px;
color: #efefef;
list-style-type: none;
margin: 0;
font-size: 18px;
min-height: 40px;
line-height: 200%;
width: 100%;
}
.menu > li
{
display: inline-block;
border-right: 1px dashed #0a2b42;
padding-right: 20px;
padding-left: 20px;
width: 145px;
}
.menu > li:last-child
{
border-right: 1px dashed #0a2b42;
}
.menu > li:first-child
{
border-left: 1px dashed #0a2b42;
}
.menu a
{
text-decoration: none;
color: #fff;
transition: transform .2s ease-in-out;
}
.menu a:hover
{
color: #0a2b42;
transform: scale(1.2);
}
h1
{
font-size: 40px;
font-weight: 500px;
color: #39a5f1;
margin-top: 40px;
margin-bottom: 20px;
}
.one
{
margin-right: auto;
margin-left: auto;
margin-bottom: 125px;
text-align: center;
width: 950px;
}
.two
{
background-color: #191d21;
margin-right: auto;
margin-left: auto;
margin-bottom: 125px;
text-align: center;
width: 950px;
}
.footer
{
width: 100%;
min-height: 50px;
background-color: #1c74b2;
text-align: center;
font-size: 16px;
padding: 17px;
margin: 0px;
}

使用这个我希望你的问题能得到解决
关于Html 和 css 背景色，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58999041/
