Как расположить форму над изображением заголовка, используя css?

0 голосов
/ 20 января 2020

Я пытаюсь расположить форму над изображением заголовка, я сделал несколько стилей css, но она тоже выходит за нижний колонтитул. Как сделать так, чтобы нижний колонтитул оставался внизу этой формы, а не под ним, и чтобы он был отзывчивым?

Мой пример кода на codepen: https://codepen.io/fatehalrabeai/pen/KKwreWd


body{
  position:relative;
}
.container{
  background-color: blue;
  paddding:30px;
  box-shadow: 0px 0px 6px 4px #c3b4b4;
  height:400px;
  position:absolute;
  top:400px;
  left:50px
}

footer{
  width:100%;
  height:300px;
  background-color:red;
}

Вы можете использовать отрицательную маржу-верх, чтобы сделать это, также вы можете использовать маржу-низ, чтобы переместить нижний колонтитул вниз. Я отредактировал ваш код: 

.container {
  position: relative;
  background-color: blue;
  padding: 30px;
  box-shadow: 0px 0px 6px 4px #c3b4b4;
  height: 400px;
  margin-top: -200px;
  z-index: 1000;
  margin-bottom: 200px;
}

footer {
  width: 100%;
  height: 300px;
  background-color: red;
}
