Ensure that the z-index of the div element is properly set

Here's the HTML code I'm working with:

<div class="caption_center">
    <h1 class="caption_header font-alpha">Making Your World More Comfortable</h1>
    <p class="caption_regular font-alpha">Let us convince you of that</p>
    <div class="caption_center_Background"></div>
</div>

and here is the CSS associated with it:

.caption_center {
    position: absolute;
    height: auto;
    text-align: center;
    color: white;
    left: 20%;
    top: 50%;
    -moz-transform: translate(0,-50%);
    -ms-transform: translate(0,-50%);
    -o-transform: translate(0,-50%);
    -webkit-transform: translate(0,-50%);
    transform: translate(0,-50%);
    width: 60%;
    /*background: rgba(138, 138, 138, 0.55);*/
    padding-top:1em;
}

.caption_center_Background {
    position:absolute;
    width:100%;
    height:100%;
    top:0;
    background-color:black;
    opacity:1;
    z-index:0;
}

.caption_header  {
    z-index:999;
}

.caption_regular {
    z-index:998;
}

After applying this code, the result should look like this:

The ultimate goal is to have a black box with an opacity of 0.5 and the text in front of it. This way, regardless of the image background, the text remains visible thanks to the semi-transparent black box.

Despite setting the z-index, the text still isn't appearing in front of the black div box. Even rearranging the elements didn't make a difference.

What could be going wrong here?

P.S. I was attempting to imitate the following fiddle.

Answer №1

Ensuring the z-index property works correctly involves specifying the position attribute. It's essential to set a value for the position attribute as the z-index does not impact elements with a position of static, which is the default setting for this attribute.

According to CSS Tricks: (emphasis added)

The z-index property in CSS manages the vertical positioning of overlapping elements, determining which one seems closer physically. z-index only affects elements with a position value other than static (the default).

.caption_center {
  position: absolute;
  height: auto;
  text-align: center;
  color: white;
  left: 20%;
  top: 50%;
  -moz-transform: translate(0, -50%);
  -ms-transform: translate(0, -50%);
  -o-transform: translate(0, -50%);
  -webkit-transform: translate(0, -50%);
  transform: translate(0, -50%);
  width: 60%;
  /*background: rgba(138, 138, 138, 0.55);*/
  padding-top: 1em;
}
.caption_center_Background {
  position: absolute;
  width: 100%;
  height: 100%;
  top: 0;
  background-color: black;
  opacity: 0.5;
  z-index: 0;
}
.caption_header {
  position: relative;
  z-index: 999;
}
.caption_regular {
  position: relative;
  z-index: 998;
}
<div class="caption_center">
  <h1 class="caption_header font-alpha">Enhancing Your Comfort</h1>
  <p class="caption_regular font-alpha">Let us convince you about it</p>
  <div class="caption_center_Background"></div>
</div>


Alternatively, setting a negative z-index on .caption_center_Background can eliminate the need to adjust positions or assign high z-index values to the text-containing elements.

.caption_center {
  position: absolute;
  height: auto;
  text-align: center;
  color: white;
  left: 20%;
  top: 50%;
  -moz-transform: translate(0, -50%);
  -ms-transform: translate(0, -50%);
  -o-transform: translate(0, -50%);
  -webkit-transform: translate(0, -50%);
  transform: translate(0, -50%);
  width: 60%;
  /*background: rgba(138, 138, 138, 0.55);*/
  padding-top: 1em;
}
.caption_center_Background {
  position: absolute;
  width: 100%;
  height: 100%;
  top: 0;
  background-color: black;
  opacity: 0.5;
  z-index: -1;
}
<div class="caption_center">
  <h1 class="caption_header font-alpha">Enhancing Your Comfort</h1>
  <p class="caption_regular font-alpha">Let us convince you about it</p>
  <div class="caption_center_Background"></div>
</div>

Answer №2

To create a visually appealing layout, simply place your text within this background div.

Here is an enhanced code snippet:

.text_center {
  position: absolute;
  height: auto;
  text-align: center;
  color: white;
  left: 20%;
  top: 50%;
  -moz-transform: translate(0, -50%);
  -ms-transform: translate(0, -50%);
  -o-transform: translate(0, -50%);
  -webkit-transform: translate(0, -50%);
  transform: translate(0, -50%);
  width: 60%;
  /*background: rgba(138, 138, 138, 0.55);*/
  padding-top: 1em;
}
.text_center_background{
  position: absolute;
  width: auto;
  height: auto;
  top: 0;
  background-color: black;
  opacity: 0.5;
  z-index: 0;
}
/*.text_header {
  z-index: 999;
}
.text_regular {
  z-index: 998;
}*/
<div class="text_center">
  <div class="text_center_background">
    <h1 class="text_header font-alpha">Making Your World More Comfortable</h1>
    <p class="text_regular font-alpha">Allow us to convince you of that.</p>
  </div>
</div>

This approach eliminates any potential position or z-index issues, and be sure to apply the necessary style opacity: 0.5; to the background div.

Implementing these changes should resolve any display problems.

Answer №3

Give this a shot...

.title_header  {
    position: absolute;
    z-index:999;
}

.title_regular {
    position: relative;
    z-index:998;
}
