Using JQuery to SlideUp with a Background Color Fading Behind an Image

I'm currently utilizing JQuery slideUp/slideDown functionality to create an overlay effect on an image. This overlay is initially hidden, only appearing when the mouse hovers over the image and sliding up from the bottom.

The issue I'm facing is that the background color of the sliding div appears behind the image rather than on top of it. Even though the z-index is set to 100, the text displays over the image while only the bottom edge of the div's background color is visible due to the margins I've applied.

Any suggestions or solutions would be greatly appreciated. Thank you!

(function($) {
  $(document).ready(function() {

$(".slider").attr("style", "display: none;");

if ($(".slider")) {
  $('.image').mouseover(function() {
    $(this).find(".slider").slideDown("400");
  }).mouseout(function() {
    $(this).find(".slider").slideUp("400");
  });
}
    
  });
}(jQuery));
.image{
  height: 300px;
  width: 300px;
  background: #000000;
}
.slider {
  background-color: #333333 !important;
  background: #333333 !important;
  background-position: 0% 100%;
  color: #ffffff;
  margin: -90px 0 0 0;
  height: 90px;
  width: 100%;
  z-index: 100 !important;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
  <div class="image">

  </div>

  <div class="slider">
    <div class="title">Title</div>
    <div class="text">Text</div>
  </div>
</div>

Answer №1

For a smoother user experience, it is recommended to set the CSS rule display: none; for the slider. Additionally, binding the mouseenter and mouseleave events to the container element will prevent the slider from jumping when the mouse moves over it.

$('.container').on("mouseenter", function() {
    $(".slider").slideDown();
  });
  $('.container').on("mouseleave", function() {
    $(".slider").slideUp("400");
  });
.container {
  width: 300px;
}
.image{
  height: 300px;
  width: 300px;
  background: #000000;
}
.slider {
  background-color: #333333;
  color: #ffffff;
  margin: -90px 0 0 0;
  height: 90px;
  width: 100%;
  display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div class="container">
  <div class="image">
  </div>
  <div class="slider">
    <div class="title">Title</div>
    <div class="text">Text</div>
  </div>
</div>

The z-index property is only effective on elements that have a specified position (such as absolute, relative, or fixed).

If you do not set a position for an element, it will default to static positioning, especially for block-level elements.

Remember to always consider the positioning of your elements when using z-index to control stacking order.
