HTML hidden display refers to using CSS or JavaScript code to control the display or hiding of elements in a Web page. This technology is widely used in website design and development, and can help websites optimize user experience and improve page interactivity.

In Web pages, it is often necessary to control the display or hiding of certain elements. For example, when the user places the mouse on a button, a drop-down menu needs to be displayed; when the user clicks on a link, some content needs to be displayed dynamically. In these scenarios, hidden display technology can come in handy.

There are many ways to implement hidden display of HTML. Here are a few of them:

1. Use CSS to implement hidden display

CSS is a kind of application A language for controlling Web page style, it can hide and display elements by setting the display attribute. When the display attribute is set to none, the element will be hidden; when the display attribute is set to other values ​​such as block or inline, the element will be displayed.

The following is an example of using CSS to implement hidden display:

<style>
    .box {
        display: none;
    }
    .button:hover + .box {
        display: block;
    }
</style>
<button class="button">显示/隐藏内容</button>
<div class="box">这是要显示/隐藏的内容</div>

In the above code, we define an element with class box and set its display attribute to none so that it is displayed by default. hide. Then a button with class button is defined. When the mouse slides over this button, the box element can be displayed, and the selector can be used to select the box element immediately following the button.

2. Use JavaScript to hide and display

JavaScript is a scripting language commonly used for Web page interaction. It can hide and display by controlling the style attribute of elements. When the style.display property is set to none, the element will be hidden; when the style.display property is set to other values ​​such as block or inline, the element will be displayed.

The following is an example of using JavaScript to implement hidden display:

<button onclick="toggle()">显示/隐藏内容</button>
<div id="box" style="display: none;">这是要显示/隐藏的内容</div>
<script>
    function toggle() {
        var box = document.getElementById("box");
        if (box.style.display === "none") {
            box.style.display = "block";
        } else {
            box.style.display = "none";
        }
    }
</script>

In the above code, we define an element with the id of box and set its style.display attribute to none to make it Hidden by default. Then a toggle() function is defined to control the display and hiding of the box element. When the button is clicked, the toggle() function will determine the current state of the box element. If it is in the hidden state, it will be displayed; if it is in the displayed state, it will be hidden.

3. Use jQuery to implement hidden display

jQuery is a JavaScript library commonly used for web page development, which can greatly simplify the coding complexity of JavaScript. You can hide and show elements using jQuery's hide() and show() methods.

The following is an example of using jQuery to implement hidden display:

<button id="toggle">显示/隐藏内容</button>
<div id="box" style="display: none;">这是要显示/隐藏的内容</div>
<script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
<script>
    $("#toggle").click(function() {
        $("#box").toggle();
    });
</script>

In the above code, we use the jQuery library and bind the toggle() function to the click event of the toggle button. When the button is clicked, the toggle() function will determine whether to show or hide based on the current state of the box element.

The above three methods can all achieve the effect of hiding and displaying HTML. Developers can choose the appropriate method according to actual needs. In actual development, the optimal solution should be selected based on the complexity and performance requirements of the page.
