我想实现下图中显示的内容,意味着使用CSS3
选择颜色。
代码目前为here。
.colors {
background: white;
width: 80%;
height: 10%;
position: absolute;
top: 60%;
display: inline-block;
overflow-x: scroll;
white-space: no-wrap;
}
.select {
float: left;
margin: 10px;
color: transparent;
z-index: 22;
background: red;
width: 20%;
}
<div class="colors">
<div class="select"></div>
<div class="select"></div>
<div class="select"></div>
<div class="select"></div>
<div class="select"></div>
<div class="select"> </div>
</div>
我制作的div没有出现。我该怎么做才能解决这个问题?

您的div未显示,因为您未向其设置任何height
。您在此white-space: no-wrap
也有语法错误,因为它应该是white-space: nowrap
。
顺便说一下,你可以简单地使用flex而不是浮动元素。使用flex时,您没有义务指定元素的高度:
.colors {
background: white;
width: 80%;
height: 100px;
margin: auto;
display: flex;
flex-wrap: nowrap; /* this is not mandatory as it's the default value*/
overflow-x: scroll;
border: 1px solid;
}
.select {
margin: 10px;
color: transparent;
background: red;
flex: 0 0 20%;
}
<div class="colors">
<div class="select"></div>
<div class="select"></div>
<div class="select"></div>
<div class="select"></div>
<div class="select"></div>
<div class="select"> </div>
</div>
或inline-block
解决方案。但是在这里你需要指定高度并注意溢出:
.colors {
background: white;
width: 80%;
height: 100px;
margin: auto;
overflow-x: scroll;
border: 1px solid;
white-space:nowrap;
}
.select {
margin: 10px;
color: transparent;
background: red;
display:inline-block;
height:calc(100% - 24px); /* You need to remove both margin and height of scroll*/
width:20%;
}
<div class="colors">
<div class="select"></div>
<div class="select"></div>
<div class="select"></div>
<div class="select"></div>
<div class="select"></div>
<div class="select"> </div>
</div>

从选择类中删除float:left方法。试试这样。
<!DOCTYPE html>
<html>
<body>
<div class="colors">
<div class="select"></div>
<div class="select"></div>
<div class="select"></div>
<div class="select"></div>
<div class="select"></div>
<div class="select"> </div>
</div>
</body>
</html>

def isBinary(num):
for i in str(num):
if i in ("0","1") == False:
return False
return True
