How to implement click hiding in css

CSS click-to-hide is a very practical function that can achieve some specific interactive effects on web pages, making the web pages more beautiful and easier to use. The following will introduce in detail the implementation method and application scenarios of CSS click hiding.

1. Implementation method

1. Use the CSS attribute display:none

This is the most basic implementation method. The principle is to set an element in HTML and use it in CSS Use the display:none attribute to hide it, and use JavaScript to control its display and hiding when needed.

Here is a specific example:

HTML code:

<div id="hide">这里是需要隐藏的内容</div>
<button onclick="toggle()">点我隐藏/显示</button>

CSS code:

#hide{
    display:none;
}

JavaScript code:

function toggle() {
    var hide = document.getElementById("hide");
    if (hide.style.display === "none") {
        hide.style.display = "block";
    } else {
        hide.style.display = "none";
    }
}

2 .Use the CSS attribute visibility:hidden

This implementation method is basically the same as the first method, except that the CSS attribute is replaced by visibility:hidden. The main difference is that an element hidden using visibility:hidden retains its footprint and does not affect the layout of surrounding elements.

The following is a specific example:

HTML code:

<div id="hide">这里是需要隐藏的内容</div>
<button onclick="toggle()">点我隐藏/显示</button>

CSS code:

#hide{
    visibility:hidden;
}

JavaScript code:

function toggle() {
    var hide = document.getElementById("hide");
    if (hide.style.visibility === "hidden") {
        hide.style.visibility = "visible";
    } else {
        hide.style.visibility = "hidden";
    }
}

3. Use the CSS3 attribute opacity

This implementation uses the new CSS3 attribute opacity, which can set the opacity of the element to hide and display the element. The difference from display and visibility is that an element hidden using opacity will still exist on the page and take up space, but its content will not be visible.

The following is a specific example:

HTML code:

<div id="hide">这里是需要隐藏的内容</div>
<button onclick="toggle()">点我隐藏/显示</button>

CSS code:

#hide{
    opacity:0;
}

JavaScript code:

function toggle() {
    var hide = document.getElementById("hide");
    if (hide.style.opacity === "0") {
        hide.style.opacity = "1";
    } else {
        hide.style.opacity = "0";
    }
}

2. Application scenarios

The specific implementation method is to place a container on the page and then put the images that need to be rotated into it. By setting the width and height of the container, as well as the position of the carousel image, and controlling the display and hiding of different images through JavaScript, the image carousel effect is achieved.
