如何使网站标题响应？

Question

我有一个包含导航栏、徽标和小描述的标题。

我需要做什么才能使其响应？导航栏没问题（汉堡图标），但我的解决方案看起来与下面的视觉图形中的不同。

这是一个 JSFiddle：http://jsfiddle.net/Mwanitete/4f6d7emr/10/

这是在小视口中显示时我想要的视觉效果：

/* Marketing business main header */

.marketing-navbar_items {
  font-family: Helvetica Neue;
  font-size: 30px;
  font-weight: normal;
  color: #FFFFFF;
}

.marketing-main-header_banner {
  background-image: url("https://svgshare.com/i/8KR.svg");
  background-size: cover;
  background-repeat: no-repeat;
  background-position: right -199px bottom;
  position: relative;
  height: 949px;
}

.marketing-main-header_details {
  display: flex;
  justify-content: center;
  flex-direction: column;
  align-items: center;
  margin-top: 30px;
}

.marketing-main-header_description p {
  font-size: 30px;
  font-family: HeaderFont;
  color: white;
  /* width: 55%; */
  text-align: center;
  margin: 50px 0px;
}

.marketing-main-header_button-primary {
  background-color: white;
  background-size: 150px 100px;
  font-size: 16px;
  border-color: transparent;
  color: #4834D4;
  font-family: Roboto Regular;
  width: 373px;
  height: 92px;
}

.marketing-main-header_button {
  margin-top: 50px;
}

@media only screen and (min-width: 375px) and (max-width: 768px) {
  img {
    width: 100%;
  }
}

.marketing-main-header_logo img {
  width: 100%;
  margin: 0px;
  padding: 0px;
}


}

我改变了你的块

.marketing-main-header_banner
{
    background-image: url("https://svgshare.com/i/8KR.svg");
    background-size: cover;
    background-repeat: no-repeat;
    background-position: right -199px bottom;
    position: relative;
    height: 949px;
}

到

.marketing-main-header_banner
{
    background-image: url("https://svgshare.com/i/8KR.svg");
    background-size: auto 1199px;
    background-repeat: no-repeat;
    background-position: center -250px;
    position: relative;
    height: 949px;
}

它非常接近您想要实现的目标。

问题是您使用“封面”作为尺寸，它将始终尝试将至少一个尺寸适合您的背景。由于 background-width 应该被削减并且 background-height 太小而不能让边缘超出可见部分，所以您必须将背景的高度设置为大于元素的高度以强制它向左和向右溢出. 最后一件事是将背景推到顶部偏移一点。

我选择了 250px 来将它添加到背景高度并作为偏移量，因为它是目前看起来最好的。您可能需要稍微调整一下。

请记住，这仅适用于出现汉堡的较小显示器。您可以将其添加到您使用媒体屏幕的响应式 CSS 文件中。
