如何使网站标题响应？

Question

我有一个标题，其中包含导航栏，徽标和简短说明。

我需要怎么做才能使其具有响应能力？导航栏还可以（汉堡图标），但是我的解决方案看起来与下面的可视图形不同。

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

在小视口中显示时，我可以看到以下内容：

/* 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;
}


}

我改变了你的封锁

.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“ cover”作为尺寸，它将始终尝试将至少其中一个尺寸适合您的背景。由于应削减background-width并且background-height太小，以至于边缘超出可见部分，因此您必须将background的高度设置为大于元素的高度，以迫使其左右溢出。 最后一件事是将背景推到顶部偏移一点。

我选择250像素将其添加到背景高度并作为偏移量，因为这是目前最好的选择。您可能需要稍微调整一下。

请记住，这仅是显示汉堡的较小显示屏的解决方案。您可以将其添加到使用媒体屏幕的响应式CSS文件中。
