我正在尝试创建缩放效果,将鼠标悬停在我的四张图片之一上.问题是大多数例子通常使用表或掩码div来应用某种效果.

下面是实现什么,我想一个例子此.

到目前为止这是我的代码.

HTML

<div id="menu">
<img class ="blog" src="http://s18.postimg.org/il7hbk7i1/image.png" alt="">
<img class ="music" src="http://s18.postimg.org/4st2fxgqh/image.png" alt="">

    margin: auto;
}

#menu img {

    cursor: pointer;
    height:475px;
    width: 350px;
}

.music {
    height: 375px;
}

.projects {
    height: 375px;
}

.bio {
    height: 375px;
}

Answer 1

那么使用CSS3 transform属性和使用scale哪个有效放大效果,这可以这样做,

HTML

<div class="thumbnail">
    <div class="image">
        <img  src="http://placehold.it/320x240" alt="Some awesome text"/>
    </div>
</div>

CSS

.thumbnail {
    width: 320px;
    height: 240px;
}

.image {
    width: 100%;
    height: 100%;    
}

.image img {
    -webkit-transition: all 1s ease; /* Safari and Chrome */
    -moz-transition: all 1s ease; /* Firefox */
    -ms-transition: all 1s ease; /* IE 9 */
    -o-transition: all 1s ease; /* Opera */
    transition: all 1s ease;
}

.image:hover img {
    -webkit-transform:scale(1.25); /* Safari and Chrome */
    -moz-transform:scale(1.25); /* Firefox */
    -ms-transform:scale(1.25); /* IE 9 */
    -o-transform:scale(1.25); /* Opera */
     transform:scale(1.25);
}

这是一个演示小提琴.我删除了一些元素以使其更简单,您可以随时添加.image隐藏的溢出来隐藏缩放图像的溢出.

zoom 属性仅适用于IE

CSS

#menu {
    text-align: center; }


.fader {
    /* Giving equal sizes to each element */
    width:    250px;
    height:   375px;

    /* Positioning elements in lines */
    display:  inline-block;

    /* This is necessary for position:absolute to work as desired */
    position: relative;

    /* Preventing zoomed images to grow outside their elements */
    overflow: hidden; }


    .fader img {
        /* Stretching the images to fill whole elements */
        width:       100%;
        height:      100%;

        /* Preventing blank space below the image */
        line-height: 0;

        /* A one-second transition was to disturbing for me */
        -webkit-transition: all 0.3s ease;
        -moz-transition:    all 0.3s ease;
        -o-transition:      all 0.3s ease;
        -ms-transition:     all 0.3s ease;
        transition:         all 0.3s ease; }

        .fader img:hover {
            /* Making images appear bigger and transparent on mouseover */
            opacity: 0.5;
            width:   120%;
            height:  120%; }

    .fader .text {
        /* Placing text behind images */
        z-index: -10;     

        /* Positioning text top-left conrner in the middle of elements */
        position: absolute;
        top:      50%;
        left:     50%; }

        .fader .text p {
            /* Positioning text contents 50% left and top relative
               to text container's top left corner */
            margin-top:  -50%; 
            margin-left: -50%; }

建议

而不是.fader { inline-block; }考虑使用一些网格系统.根据您的偏好技术,您可以选择Foundation,Susy,Masonry或他们的替代品.

Answer 3

.aku { 
    transition: all .2s ease-in-out; 
}

.aku:hover {
    transform: scale(1.1); 
}

Answer 4

我喜欢使用背景图片.我发现它更容易,更灵活:

DEMO

CSS:

#menu {
    max-width: 1200px;
    text-align: center;
    margin: auto;
}
.zoomimg {
    display: inline-block;
    width: 250px;
    height: 375px;
    padding: 0px 5px 0px 5px;
    background-size: 100% 100%;
    background-repeat: no-repeat;
    background-position: center center;
    transition: all .5s ease;
}
.zoomimg:hover {
    cursor: pointer;
    background-size: 150% 150%;
}
.blog {
    background-image: url(http://s18.postimg.org/il7hbk7i1/image.png);
}
.music {
    background-image: url(http://s18.postimg.org/4st2fxgqh/image.png);
}
.projects {
    background-image: url(http://s18.postimg.org/sxtrxn115/image.png);
}
.bio {
    background-image: url(http://s18.postimg.org/5xn4lb37d/image.png);
}

HTML:

<div id="menu">
    <div class="blog zoomimg"></div>
    <div class="music zoomimg"></div>
    <div class="projects zoomimg"></div>
    <div class="bio zoomimg"></div>
</div>

DEMO 2与叠加

Answer 5

只是:

.grow { transition: all .2s ease-in-out; }

这将允许元素通过css分配动画.

.grow:hover { transform: scale(1.1); }

这将使它成长!

Answer 6

.item:hover img 
{
 -moz-transform: scale(1.3);
 -webkit-transform: scale(1.3);
 transform: scale(1.3);
}

这样你就可以用简单的动画缩放任何图像.如果你需要一个完整的教程,这里有一个官方教程:http://talkerscode.com/webtricks/image-zoom-in-on-hover-using-css3.php
