Question

我正在尝试获得一个CSS翻转动画，该动画基于鼠标指针在按钮上的悬停效果。现在您可以在this codepen看到类似的内容在此Codepen示例中，将鼠标指针悬停在卡片上时，您将获得一个翻转动画。

我有以下html代码：

<!DOCTYPE html>

        <meta charset="utf-8" />
        <title>Card Flipped</title>

                                <!-- Simple card -->

                             <div class="flipper">

                                            up the bulk of the card's content. Some quick example text to build on the card title and make up.</p>
                                        <a href="javascript: void(0);" class="btn btn-primary">Buy</a>
                                        <a href="javascript: void(0);" class="btn btn-primary view-details">View Details</a>
                                    </div> <!-- end card-body-->
                                </div> <!-- end card-->
                             </div>

                                    <div class="back">
                                        <h1>Do you like it?</h2><!-- back content -->
                                    </div>
                                </div>
                            </div>

        </div>
        <!-- END wrapper -->

        <script src="assets/js/app.min.js"></script>
    </body>
</html>

此CSS代码：

/* FLIP DOUBLE SIDE START ANIMATION CODE */
/* entire container, keeps perspective */
/* flip the pane when hovered */

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

/*
.view-details:hover .flipper {
    transform: rotateY(180deg);
  }
*/

.flip-container, .front, .back { /*Attention*/
    width: 280px;
    height: 480px;
}


/* flip speed goes here */
.flipper {
    transition: 0.6s;
    transform-style: preserve-3d;

    position: relative;
}

/* hide back of pane during swap */
.front, .back {
    backface-visibility: hidden;

    position: absolute;
    top: 0;
    left: 0;
}

/* front pane, placed above back */
.front {
    z-index: 2;
    /* for firefox 31 */
    transform: rotateY(0deg);
}

/* back, initially hidden pane */
.back {
    transform: rotateY(180deg);
}
/* FLIP DOUBLE SIDE END CODE ANIMATION*/

但是我想得到的是，当您将鼠标指针放在viw详细信息按钮上时，您会得到整个卡片的翻转动画。视图详细信息按钮包含一个称为“视图详细信息”的类。所以我尝试更改css行：

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

对于另一个：

.view-details:hover .flipper{   transform: rotateY(180deg);
        }

但是显然没有任何反应。顺便说一下，我从David Walsh web page

获得了CSS代码和html代码的一部分

Answer 1

什么都没有发生，因为您试图为仅使用CSS的孩子设置父选择器动画。不幸的是，当前无法仅使用CSS选择元素的父级。您将需要使用这样的Javascript / jQuery解决方案来达到您想要的效果。

$('a.view-details').mouseover(function() {
  $(this).parents('.flipper').css('transform', 'rotateY(180deg)');
}).mouseout(function() {
	$(this).parents('.flipper').css('transform', '');
});

/* FLIP DOUBLE SIDE START ANIMATION CODE */
/* entire container, keeps perspective */

.flip-container,
.front,
.back {
	/*Attention*/
	width: 280px;
	height: 480px;
}

/* flip speed goes here */
.flipper {
	transition: 0.6s;
	transform-style: preserve-3d;
	position: relative;
}

/* hide back of pane during swap */
.front,
.back {
	backface-visibility: hidden;
	position: absolute;
	top: 0;
	left: 0;
}

/* front pane, placed above back */
.front {
	z-index: 2;
	/* for firefox 31 */
	transform: rotateY(0deg);
}

/* back, initially hidden pane */
.back {
	transform: rotateY(180deg);
}
/* FLIP DOUBLE SIDE END CODE ANIMATION*/
