Question

我在引导程序中有一个导航栏，我正在尝试将导航栏项目设计为具有背景颜色，但是当我尝试这样做时，仍然有一些空间不会占用该背景颜色。如何让它覆盖整个屏幕？

＆＃13;

@media (max-width: 992px) {
  .navbar-collapse li a {
    /* style goes here */
    margin-top: 5px;
    background-color: aqua;
    border: 2px solid black;
  }
}

Answer 1

.navbar的填充为1rem，因此您需要在nav-link

上对此进行抵消

@media (max-width: 992px) {
  .navbar-nav .nav-item .nav-link {
    /* style goes here */
    margin-top: 5px;
    background-color: aqua;
    border: 2px solid black;
    margin-left: -1rem;
    margin-right: -1rem;
    padding-left: 1rem;
  }
}

 @media (max-width: 992px) {
  .nav-link > span {
    /* style goes here */
    margin-top: 5px;
    background-color: aqua;
    border: 2px solid black;
  }
}
