我目前有一个搜索栏,背景是透明的,文字和图标是白色的。
我想更改它,以便底部栏变为红色/粉红色以及此处显示的上方栏:
HTML:
<form class="form" id="travel-wizard-v2-form">
<ul class="errors" style="display:none;">
<li class="error tw2-location-error" style="display:none;">Please tell us where you would like to travel to</li>
<li class="error tw2-search-term-error" style="display:none;">Please enter a search term of at least 3 chars long.</li>
</ul>
<div class="input-group destination-cont">
<input type="text" data-validate="true" data-validatetype="empty" id="tw2-destination" data-provide="typeahead" placeholder="Hotels Destination Placeholder" autocomplete="off">
<span class="icon icon-search input-icon"></span>
</div>
CSS:
.travel-wizard .travel-wizard-content .input-group input {
height: 50px;
background-color: rgba(255,255,255,.25);
border: none;
float: left;
border-top-right-radius: 0;
border-bottom-right-radius: 0;
box-sizing: border-box;
color: #ffffff;
font-size: 13px;
font-weight: 100;
padding-left: 10px;
}
.travel-wizard .travel-wizard-content .icon.icon-search {
top: 17px;
display: block;
background: 0 0;
margin: 0;
color: #ffffff;
}
因此,我只需更改颜色即可:黑色; background-color:这两个CSS的文件都是粉红色,它会使它看起来与上面的错误栏相同。但是我需要它的背景变成粉红色,只有当用户输入无效时,它的文字和图标才会变黑!
答案 0 :(得分:1)
如果我们可以假设[{"SMS":"hello","NUM":12345},{"SMS":"bye","NUM":54321}]
元素仅在发生错误时出现在dom中,则可以使用兄弟选择器:
my $json = JSON->new->utf8;
my $perl_data = $json->decode($content);
print ref($perl_data) . "\n";
