你也可以使用伪元素方法,但是为了开始而不是混淆,我使用了一个额外的元素,它将是箭头。 评论中的代码说明
要了解箭头的创建方式,您需要先看一下此演示:How CSS triangles work
.image {
width: 250px;
height: 200px;
background: black;
position: relative;
overflow: hidden;
}
.image img {
transition: all ease 1s;
}
.image:hover img { /* Darkening effect on mouseover */
background: black;
opacity: 0.7;
}
.image .arrow { /* Creates a half triangle with top and left arrow transparent */
opacity: 0;
border-color: transparent #f2f2f2 #f2f2f2 transparent;
transition: all ease 1s;
position: relative;
}
.image:hover .arrow { /* Mouseover effect */
opacity: 1;
font-family: Roboto;
font-size: 36px;
text-align: center;
border-image: none;
border-style: solid;
border-width: 45px;
position: absolute;
bottom: 0;
font-weight: normal;
width: 0;
height: 0;
right: 0;
}
.image:hover .arrow {
border-image: none;
border-style: solid;
border-width: 45px;
bottom: 0;
display: block;
font-family: Roboto;
font-size: 36px;
font-weight: normal;
height: 0;
opacity: 1;
position: absolute;
right: 0;
text-align: center;
width: 0;
}
.image .arrow {
border-color: transparent #f2f2f2 #f2f2f2 transparent;
opacity: 0;
position: relative;
transition: all 1s ease 0s;
}
.image .arrow span {
left: 5px;
position: relative;
top: -10px;
}
<div class="image">
<img src="http://lorempixel.com/250/200/sports" />
<div class="arrow"><span>></span></div>
</div>
