HTML, CSS and jQuery: Tips for realizing image flipping effects

In modern web design, in order to increase the interactivity and attractiveness of the page, some elements are often added. Special effects to enhance user experience. Among them, the picture flipping effect is a common and eye-catching effect that can make static pictures vivid and interesting.

In this article, we will introduce how to use HTML, CSS and jQuery to achieve image flipping effects, and provide specific code examples for readers' reference.

1. Preparation

First, we need to prepare some picture materials and create a container for them.

<div class="flip-container">
  <div class="flipper">
    <div class="front">
      <img src="/static/imghwm/default1.png"  data-src="image1.jpg"  class="lazy" alt="Image 1">
    </div>
    <div class="back">
      <img src="/static/imghwm/default1.png"  data-src="image2.jpg"  class="lazy" alt="Image 2">
    </div>
  </div>
</div>

In the above code, we created a div named flip-container as the wrapping container, and created two divs in it: flipper and front and back. Flipper is responsible for controlling the flip effect, while front and back are used to accommodate the pictures that need to be flipped.

2.CSS style settings

Next, we need to add some CSS styles to these elements to achieve the flip effect.

.flip-container {
  perspective: 1000px;
  width: 200px;
  /* 设置适当的宽度和高度 */
  height: 200px;
}

.flipper {
  position: relative;
  transform-style: preserve-3d;
  transition: transform 0.6s;
  transform-origin: 50% 50%;
  /* 根据需要调整翻转速度和翻转位置 */
  width: 200px;
  height: 200px;
}

.front, .back {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  backface-visibility: hidden;
}

.front {
  z-index: 1;
  /* 设置适当的背景颜色或样式 */
  background-color: #fff;
}

.back {
  transform: rotateY(180deg);
  /* 设置需要翻转的图像 */
}

.flip-container:hover .flipper {
  transform: rotateY(180deg);
}

In the above code, we first set the perspective attribute for flip-container to provide a perspective effect and increase realism. Then, we set various CSS properties of flipper to support the 3D flip effect. The front and back elements are used to display the front and back pictures respectively, and hide the back elements through the backface-visibility attribute.

3.jQuery script to implement animation effects

Finally, we use jQuery to create animation effects so that the image can be flipped when the mouse is hovered.

$(document).ready(function() {
  $('.flip-container').hover(function() {
    $(this).find('.flipper').addClass('flip');
  }, function() {
    $(this).find('.flipper').removeClass('flip');
  });
});

In the above code, we use the .hover() function to add a mouse hover event to the .flip-container. When the mouse is hovered over the container, jQuery will dynamically add the .flip class to trigger the flip effect in CSS. When the mouse leaves the container, jQuery will remove the .flip class to achieve the restoration effect of the element.

Summary

Through the combination of HTML, CSS and jQuery, we can easily achieve image flipping effects. By adjusting various properties in CSS, we can obtain flip effects with different styles and effects. Using jQuery to handle mouse events can further improve the user interaction experience.

I hope the tips and code examples provided in this article will be helpful to readers and make it easier and more enjoyable to implement image flipping effects.
