Question

为了进行自学，我试图建立一个搜索字段，但是我正在尝试两个问题。

1。如果文字太长，它将显示在搜索图标的后面。我该如何预防？

2。即使我添加了right:0;

，为什么图标和右边框之间仍然有空格

相对代码：

.search i{
position: absolute;    
top:50%;
right:0;
transform: translateY(-50%);
font-size: 35px;
color: dimgray;
background-color:green;
}

.search-container{
    display:flex;
    width:70%;
}
.search{
    width:100%;
    position:relative;
}
.search input{
    height:50px;
    padding:4px 0 4px 30px;
    font-size: 20px;
}
.search i{
    position: absolute;
    top:50%;
    right:0;
    transform: translateY(-50%);
    font-size: 35px;
    color: dimgray;
}

</html>

Answer 1

您可以在输入中添加一个权限padding，并将box-sizing设置为border-box。
之所以有空格，是因为该图标相对于输入没有未放置在右侧，但是相对于<div class="search"> 却是，因为这是它的第一个定位（非静态）祖先元素。而且，如果您使用浏览器对其进行检查，则图标div的结尾位置。

这是固定的代码段：

.search-container{ display:flex; width:70%; } .search{ width:100%; position:relative; } .search input{ height:50px; padding:4px 50px 4px 30px; font-size: 20px; box-sizing: border-box; } .search i{ position: absolute; top:50%; right:10px; transform: translateY(-50%); font-size: 35px; color: dimgray; }

Answer 2

这是您认为可以满足您要求的修改后的代码。我已从您的搜索输入中删除了user@example.com false : 405类，因为父节点具有相同的类。

search

.search-container{
    display:flex;
    width:70%;
}
.search{
    width:100%;
    position:relative;
    display: flex;
    flex-direction: row;
    border: 1px solid black;
}

.search:focus-within {
  outline-width: 1px;
  outline-color: rgb(166,200,255);
  outline-style: solid;
}

.search input{
    height:50px;
    width: 90%;
    padding:4px 0 4px 30px;
    font-size: 20px;
    border: none;
    outline: none;
}

.search i{
    display: flex;
    width: 10%;
    justify-content: center;
    align-items: center;
    font-size: 35px;
    padding: 0 .5em 0 .5em;
    color: dimgray;
}

来自http://jsfiddle.net/Sadhana/2LHh9/：

.search_box {
    background:url("http://png-5.findicons.com/files/icons/980/yuuminco/256/search.png");
    background-size:20px 20px;
    background-repeat:no-repeat;
    background-position: right;
    padding-right: 20px !important;
    padding-top: 2px !important;
    padding-bottom: 2px !important;
    padding-left: 5px !important;
    float: left;
}
