Answer 1

Answer №1

Although it may appear basic, the question at hand is far from banal. Many individuals struggle with this issue on a regular basis if they are not well-versed in handling it. The manner in which you position a form above an image can greatly affect the outcome.

Are you setting the image as the background of the Form?
Are you utilizing css absolute or relative positioning?
Are you employing javascript/jquery to position the element?

One crucial point to consider when layering one element over another is to ensure that it has been taken out of the document flow, typically achieved by using a position:absolute; or position:relative; declaration in your css. Once this is done, the element will be placed absolutely or relatively in relation to the nearest non-statically positioned element containing it. In the example snippet provided, you will observe that clicking inside the red box results in all elements moving to that location while maintaining their spatial relationship.

var add = 20;
var leftCt = $("div#left_ct");
var cnt = $('div#container');
var bkg = $('div#background_relative');

cnt.on("click", function(e) {
  var left = e.pageX - cnt.position().left - 10;
  var top = e.pageY - cnt.position().top - 30;
  bkg.css({
    left: left,
    top: top
  });
  leftCt.html(left);
})

div#container {
  padding:10px;
  position: relative;
  background-color: salmon;
  width: 600px;
  height: 600px;
}
div#background_relative {
  display: block;
  margin: 10px;
  background-color: lightgreen;
  position: relative;
  width: 300px;
  height: 300px;
}
div#background_relative>* {
  left: 0;
  background-color: lightblue;
  position: absolute;
}
img {
  top: 20px;
}
form#form_over_image {
  background-color: yellow;
  z-index: 1;
  left: 10%;
  top: 100px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='left_ct'></div>
<div id='container'>
  Container has position:relative
  <div id='background_relative'>
    Background has position:relative
    <img src='' alt='image has position:absolute' width=200 height=200 />
    <form id='form_over_image'>
      <div>form has position: absolute</div>
      <input type='text' value='' />
    </form>
  </div>

Answer №2

Instead of positioning the button absolutely relative to its containing div, you are currently placing it with respect to the entire window. This approach is not ideal when using an image as a background/layout in your scenario, making it difficult to achieve your desired outcome.
