引導程序中兩列窗體之間不需要的空間

Question

我想創建類似於此的輸入框的工具提示。

但是，當我嘗試在我的代碼中輸入框和工具提示之間留下了太多的空間，如下圖所示。我爲輸入框和工具提示使用了兩個不同的列。

我的用戶名&提示行代碼如下：

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/> 
 

 
<div class="row"> 
 
<div class="col-xs-0 col-sm-3"></div> 
 
<div class="col-xs-11 col-sm-4"> 
 
    <form action="<?php echo base_url('loginclient/verify'); ?>" method="post" name="login_form" onsubmit=" return validateForm()"> 
 
    <div class="form-group"> 
 
    <input type="text" class="form-control" name="username" placeholder="username" autofocus="autofocus" pattern="([^ ]){6,}" title="Minimum length is 6, without any space." required="" /> 
 
    </div> 
 
</div> 
 
<div class="col-xs-1 col-sm-1" style="background-color:pink"> 
 
    <a class="pull-left" data-toggle="tooltip" data-placement="bottom" title="Enter your username">?</a> 
 
</div> 
 
<div class="col-xs-0 col-sm-4"></div> 
 
</div>

列類有默認填充

Answer 1

引導電網系統，以便使用內聯CSS開銷填充像

<div class="col-xs-1 col-sm-1" style="background-color:pink; padding:0px !important;"> 

Answer 2

父母的div形式有填充右均爲15px

（也填充左），您可以將樣式應用於改正它：

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/> 
 

 
<div class="row"> 
 
<div class="col-xs-0 col-sm-3"></div> 
 
<div class="col-xs-11 col-sm-4" style="padding-right:0;"> 
 
    <form action="<?php echo base_url('loginclient/verify'); ?>" method="post" name="login_form" onsubmit=" return validateForm()"> 
 
    <div class="form-group"> 
 
    <input type="text" class="form-control" name="username" placeholder="username" autofocus="autofocus" pattern="([^ ]){6,}" title="Minimum length is 6, without any space." required="" /> 
 
    </div> 
 
</div> 
 
<div class="col-xs-1 col-sm-1" style="background-color:pink"> 
 
    <a class="pull-left" data-toggle="tooltip" data-placement="bottom" title="Enter your username">?</a> 
 
</div> 
 
<div class="col-xs-0 col-sm-4"></div> 
 
</div>

關注HTML結構是這樣的。這是使用工具提示和文本框的最佳方式。

.input { 
 
    position: relative; 
 
    padding-right: 100px; 
 
} 
 
.qtooltip { 
 
    position: absolute; 
 
    top:5px; 
 
    right:75px; 
 
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/> 
 
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<form action="<?php echo base_url('loginclient/verify'); ?>" method="post" name="login_form" onsubmit=" return validateForm()"> 
 
    <div class="form-group"> 
 
    <div class=" input"> 
 
     <input type="text" class="form-control" name="username" placeholder="username" autofocus="autofocus" pattern="([^ ]){6,}" title="Minimum length is 6, without any space." required="" /> 
 
     <div class="qtooltip"> 
 
     <a class="pull-left" data-toggle="tooltip" data-placement="bottom" title="Enter your username">?</a> 
 
     </div> 
 
    </div> 
 
    </div>

這發生，因爲列創建經由填充水槽（柱含量之間的間隙）。該填充通過.rows上的負邊距在第一行和最後一列的行中偏移。

最好的辦法是使用.input-group-addon

$(function() { 
 
    $('[data-toggle="tooltip"]').tooltip() 
 
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.1/jquery.min.js"></script> 
 
<!-- Latest compiled and minified CSS --> 
 
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"> 
 
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> 
 
<style> 
 
    .input-group { 
 
    position: static; 
 
    } 
 
    .input-group-addon { 
 
    background-color: #fff; 
 
    border: 0; 
 
    } 
 
    .input-group .form-control { 
 
    border-radius: 4px!important; 
 
    } 
 
</style> 
 

 
<div class=container> 
 
    <div class="input-group" style="width:250px;"> 
 
    <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)"> 
 
    <span class="input-group-addon"><span class="glyphicon glyphicon-question-sign" data-toggle="tooltip" data-placement="right" title="Tooltip on right"></span></span> 
 
    </div> 
 

 
</div>
