我有一个header
,其下面是一个包含两张中等大图片的容器,当我调整页面时出现问题 {{1} }往往在我的header
下面,我希望它做什么是button-container
推动header
向下
jsfiddle: https://jsfiddle.net/Lw0pb53d/8/
通过更改button-container
- > button-containers
到transform:translate(-50%, -50%)
我有点设法让它发挥作用但是在调整transform:translate(-50%, 0%)
元素的大小后,太多了通过填充边距,我把它放在中心但是然后在纵向模式下容器再次超过标题
button-container

/*Header*/
h1 {
text-transform: uppercase;
width: 100%;
font-size: 9vw;
text-align: center;
margin-top: 4vh;
border: 1px solid #000;
}
/*Containers*/
#button-container {
padding: 0;
margin: 0;
list-style: none;
display: flex;
-webkit-flex-flow: row wrap;
justify-content: space-around;
margin-top: 35vh;
margin-left: 50vw;
transform: translate(-50%, -50%);
width: 90vw;
/*width: 90vw;
height: 60vh;*/
align-items: baseline;
background: linear-gradient(to right, transparent 0%, #fff 33%, #fff 66%, transparent 100%);
border: 1px solid #000;
}
#button-container li {
position: relative;
display: inline-block;
cursor: pointer;
}
/* Text block */
#button-container .html-text-block,
.cs-text-block {
position: absolute;
bottom: 4px;
width: 100%;
height: 30%;
box-sizing: border-box;
background-color: #fff;
padding-left: 5px;
box-shadow: 0 3px 6px rgba(0, 0, 0, 0.16), 0 3px 6px rgba(0, 0, 0, 0.23);
transition: box-shadow 0.5s cubic-bezier(.25, .8, .25, 1), transform 0.5s cubic-bezier(.25, .8, .25, 1);
}
/* Logo Sizing*/
#button-container .htmllogo,
#button-container .csharplogo {
width: 440px;
}

你的标题是一个h1元素(在语义上不正确:h1 - > h6应该用于显示标题元素,即标题),因此它具有display
属性默认设置为inline
。
将其包裹在div中:它的display: block
默认属性会将ul向下推

通过在<div id="flex-container"> // THE CONTAINER //
<ul id="button-container">
<li>
<a id="html-modal-button">
<img class="htmllogo" src="https://upload.wikimedia.org/wikipedia/commons/thumb/3/38/HTML5_Badge.svg/600px-HTML5_Badge.svg.png">
<div class="html-text-block">
<h2>HTML</h2>
<p>My web projects</p>
</div>
</a>
</li>
<li>
<a id="cs-modal-button">
<img class="csharplogo" src="https://camo.githubusercontent.com/0617f4657fef12e8d16db45b8d73def73144b09f/68747470733a2f2f646576656c6f7065722e6665646f726170726f6a6563742e6f72672f7374617469632f6c6f676f2f6373686172702e706e67">
<div class="cs-text-block">

</ul>
</div>
所以:
<强> HTML:强>
#flex-container {
display: flex;
justify-content: center;
align-items: center;
}
<强> CSS 强>
margin-top: 35vh;
margin-left: 50vw;
transform: translate(-50%, -50%);
并删除:
var aeqr;
var qrurl = new QRCode(document.getElementById("qrcode"), {
width : 140,
height : 140
});
var qrdest = "text";
aeqr = document.getElementById("qrjs"); //getting ID from qrcode.js
aeqr.onload = function() {
qrurl.drawImage(aeqr, 0, 0, 120, 120);
var qrdataURL = qrcanvas.toDataURL();
}
qrurl.makeCode(qrdest);
