Question

我正在尝试放置submenu div和由背景制成的横幅。

问题是它们没有填充屏幕宽度。左右两侧都有小的空白。同样在我的真实应用中，单击按钮后会出现submenu div，因此必须将其向下推。我的意思是，如果我将submenu设为绝对位置，则可以达到100％的宽度，但是横幅div的下方不被按下。 >

HTML：

 <div>
      <div class="subMenu"></div>
<div class="mainBanner">
  <a class="mainBannerLink" href="/products/category/all" data-auto-id="true" id="gift_guide-category-minimalist-591-0">
    <span class="mainBannerLinkContent">
        <h1>
          <span class="mainBannerTitle">Considered carry goods to<br></br>enhance your everyday</span>
        </h1>
        <button class="mainBannerLinkContentShopNow">
          SHOP NOW
        </button>
    </span>
  </a>
</div>

</div>

CSS：

.mainBanner{
    position: relative;
    padding-top: 59vh;

    background-image: url(https://bellroy.imgix.net/cms_images/1912/homepage-banner-test-1-1800x660.jpg?auto=format&fit=max);
    background-size: cover;
    width:100%;

    background-position: center center;
    background-repeat: no-repeat;
    cursor: pointer;
}
.mainBannerLink{
    position: absolute;
    display: block;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    text-decoration: none;
    z-index: 3;
}
.mainBannerLinkContent{
    position: relative;
    display: block;
    top: 50%;
    transform: translateY(-50%);

    text-align: center;
}
.mainBannerLinkContentShopNow{
    font-family: 'Lato', sans-serif;

    -webkit-font-smoothing: antialiased;
    color: #626161;
    font-weight: bold;
    letter-spacing: 2.5px;
    font-size: 12px;
    text-transform: uppercase;
    padding: 0 15px;
    line-height: 35px;
    border: 0;
    background-color: #fff;
    cursor: pointer !important;
}
.mainBannerTitle{
    font-family: 'Lato', sans-serif;

    font-weight: bold;
    line-height: 1.3;
    -webkit-font-smoothing: antialiased;

    margin: 0 0 30px 0;
    padding: 0;
    letter-spacing: 1px;
}
.subMenu{
    display: flex;
    position:relative;
    left: 0;
    width: 100%;
    background: rgb(33, 49, 94);
    height: 100px;
    overflow: hidden;
    border-top: 5px solid #eee;
    opacity: 1;
    z-index: 1;
}
