How to implement click-to-hide display in css

CSS Click to Hide Show

In today’s Internet era, the focus of web design has shifted from simple static display to a more advanced interactive experience. Among them, hiding and showing is one of the most commonly used interaction methods. This method allows users to obtain the required information more conveniently and can greatly reduce redundant content on the page. In CSS, there are several methods to hide and show, and this article will introduce them one by one.

1. Use the display attribute

The value of the display attribute in CSS controls whether the element is displayed or hidden. Values ​​include:

• none: The element will be completely removed from the page and will be completely invisible to the layout.
• block: The element is displayed as a block-level element, meaning it occupies an entire line.
• inline: The element is displayed as an inline element, meaning it takes up the same space as the text.
• inline-block: The element is displayed as an inline element, but attributes such as width and height can be set.

Using the display attribute, we can hide and display by adding or removing the display attribute of the element. The sample code is as follows:

HTML code:

<div class="box">
  <p>隐藏的内容</p>
</div>
<button id="toggle">显示/隐藏</button>

CSS Code:

.box {
  display: none;
}

JavaScript code:

document.getElementById("toggle").addEventListener("click", function() {
  var box = document.querySelector(".box");
  if(box.style.display === "none") {
    box.style.display = "block";
  } else {
    box.style.display = "none";
  }
});

2. Use the opacity attribute

The opacity attribute controls the transparency of the element to achieve the effect of hiding or showing. When the opacity property is set to 0, the element will be completely transparent, so it cannot be seen. When the opacity property is 1, it is fully visible. But it will still take up its space on the page.

HTML code:

<div class="box">
  <p>隐藏的内容</p>
</div>
<button id="toggle">显示/隐藏</button>

CSS code:

.box {
  opacity: 0;
  transition: opacity 0.5s ease-in-out;
  pointer-events: none;
}

.box.show {
  opacity: 1;
  pointer-events: auto;
}

JavaScript code:

document.getElementById("toggle").addEventListener("click", function() {
  var box = document.querySelector(".box");
  box.classList.toggle("show");
});

3. Use the visibility attribute

<div class="box">
  <p>隐藏的内容</p>
</div>
<button id="toggle">显示/隐藏</button>

.box {
  visibility: hidden;
}

.box.show {
  visibility: visible;
}

document.getElementById("toggle").addEventListener("click", function() {
  var box = document.querySelector(".box");
  box.classList.toggle("show");
});
