我一直试图让以下代码工作数小时,但没有成功......你能不能帮助我让项目div居中(即使页面放大和缩小)?
这是我的HTML& CSS:
#bottom {
position: absolute;
top: 100%;
left: 0;
right: 0;
background-color: #FFF;}
#secondsection {
background-size: 100% auto;
background-size: cover;
color: #eaeaf0;
margin-left: 7%;
margin-right: 7%;
padding-top: 35px;
padding-bottom: 35px;
position: relative;}
#ss_top {
width: 100%;
height: 100%;}
.ss_title {
display: inline;
float:left;
color: #000000;
font-family: 'Eurostile';
font-size: 35px;
text-transform: uppercase;}
.ss_title2 {
color: #a5a5a5;}
#gallerybutton {
position: relative;
display: inline;
float: right;
margin-right: 0%;
margin-top: 50px;
padding: 20px;
background-color: #000;
text-decoration: none;
border: none;
color: #FFF;
text-transform: uppercase;}
#projects {
position: relative;
margin-left: auto;
margin-right: auto;
max-width: 2000px;
padding: 175px 0px 0px 0px;}
#pr_one, #pr_two {
display: block;}
.pr_img {
float: left;
display: inline;
margin-right: 1%;
margin-bottom: 1%;}
#viewprofilebutton {
position: relative;
left: -75px;
margin-left: 50%;
margin-top: 3.5%;
margin-bottom: 2.5%;
padding: 20px;
background-color: #000;
text-decoration: none;
border: none;
color: #FFF;
text-transform: uppercase;}

<div id="secondsection">
<div id="ss_top">
<p class="ss_title">A selection of projects<br /><span class="ss_title2">I've worked on lately</span></p>
<button type="button" id="gallerybutton">See everything</button>
</div>
<div id="projects">
<div id="pr_one">
<div class="pr_img"><a target="_blank" href=""><img src="images/pr_nfs.jpg" alt="" width="488px" height="272px"></a></div>
<div class="pr_img"><a target="_blank" href=""><img src="images/pr_nfs.jpg" alt="" width="488px" height="272px"></a></div>
<div class="pr_img"><a target="_blank" href=""><img src="images/pr_nfs.jpg" alt="" width="488px" height="272px"></a></div>
</div>
<div id="pr_two">
<div class="pr_img"><a target="_blank" href=""><img src="images/pr_nfs.jpg" alt="" width="488px" height="272px"></a></div>
<div class="pr_img"><a target="_blank" href=""><img src="images/pr_nfs.jpg" alt="" width="488px" height="272px"></a></div>
<div class="pr_img"><a target="_blank" href=""><img src="images/pr_nfs.jpg" alt="" width="488px" height="272px"></a></div>
</div>
</div>
<a href="#thirdsection"><button type="button" id="viewprofilebutton">See my work</button></a>
</div>

这是一个开始。看看下面的CSS:
#bottom {
position: absolute;
top: 100%;
left: 0;
right: 0;
background-color: #FFF;}
#secondsection {
background-size: 100% auto;
background-size: cover;
color: #eaeaf0;
margin-left: 7%;
margin-right: 7%;
padding-top: 35px;
padding-bottom: 35px;
position: relative;
border: 1px dotted red;
}
#ss_top {
width: 100%;
height: 100%;
border: 1px dotted blue;
overflow: auto;
}
#ss_top p {
margin: 0;
}
.ss_title {
display: inline-block;
color: #000000;
font-family: 'Eurostile';
font-size: 35px;
text-transform: uppercase;}
.ss_title2 {
color: #a5a5a5;}
#gallerybutton {
position: relative;
display: inline;
float: right;
margin-right: 0%;
margin-top: 50px;
padding: 20px;
background-color: #000;
text-decoration: none;
border: none;
color: #FFF;
text-transform: uppercase;}
#projects {
position: relative;
margin-left: auto;
margin-right: auto;
max-width: 2000px;
padding: 175px 0px 0px 0px;
border: 1px dashed blue;
}
#pr_one, #pr_two {
display: block;
border: 2px dashed blue;
overflow: auto;
text-align: center;
}
.pr_img {
display: inline-block;
width: 30%;
margin-right: 1%;
margin-bottom: 1%;
}
.pr_img img {
display: inline-block;
width: 100%;
height: auto;
}
#viewprofilebutton {
position: relative;
left: -75px;
margin-left: 50%;
margin-top: 3.5%;
margin-bottom: 2.5%;
padding: 20px;
background-color: #000;
text-decoration: none;
border: none;
color: #FFF;
text-transform: uppercase;}
我开始摆脱标题中的花车#ss_top
,你不需要它。
对于带有图像的#projects
面板,浮动让你遇到麻烦
定心。
在#pr_one
和#pr_two
上,添加text-align: center
,然后在display: inline-block
上使用.pr_img
,这将使您的图片居中对齐(给予/获取一些边距) ,然后应用合适的宽度30%
,以便图像自动缩放以形成三行。
现在的诀窍是将display: inline-block
应用于图像(.pr_img img
),以便您
现在可以使用边距来控制上/下/左/右间距。
请参阅演示:http://jsfiddle.net/audetwebdesign/rmtpy6t0/
注意:你还有一些要做的事,但至少这可以澄清与居中和浮动元素相关的问题。
响应式设计:如果您需要连续2或3张图片,具体取决于屏幕尺寸,则需要了解媒体查询。但是,因为您在div
中包装了3张图片,所以每行锁定3张图片,但这可能没问题。

如果您想将图片居中,请在css中进行更改:
.pr_img {
/* float: left; */
display: block;
/* margin-right: 1%; */
/* margin-bottom: 1%; */
margin: 0 auto;
}

而不是使用margin-left:auto和margin-right:auto add margin:auto
#projects {
position: relative;
margin:auto;
max-width: 2000px;
padding: 175px 0px 0px 0px;
}

答案 4 :(得分:0)
.pr_img {
text-align: center;
left: 0;
right: 0;
display: block;
margin: 0 auto;
}
这对我有用
