php - 格式化网页以进行打印

Question

我有一个显示 div 标签的循环，从数据库返回值。我正在使用 twitter bootstrap 进行布局。该页面按预期显示文本，如列表。但是，我添加了一个链接以启用打印。当我单击链接打印列表时，它会在循环迭代中添加一个空格:

我想显示为一个列表，左边没有添加边距。

<div class="row">
   <ul class="unstyled">


<?php

foreach ($user_id3 as $userid) {


$sql = mysqli_query($con, "SELECT u.*, i.item_id, i.item_name, ui.date FROM user_items ui 
INNER JOIN users u on ui.user_id = u.user_id 
INNER JOIN items i on ui.item_id = i.item_id 
WHERE u.user_id = '$userid'");

if(!$sql) {
   echo "error sql: " . mysqli_error($con);
}

$item_ids = array();
$item_names = array();
$user_companys = array();
$user_emails = array();
$user_dates = array();
  while($row = mysqli_fetch_array($sql)) {

       $user_ids = $row['user_id'];

提前致谢。

Answer 1

是的，你可以做到。您需要使用零 margin 和 padding 重置 ul。这将删除额外的间距。

例如，

WORKING DEMO

HTML 代码:

<ul class="noLeftMargin">
    <li>This is a list item</li>
    <li>This is a list item</li>
    <li>This is a list item</li>
    <li>This is a list item</li>
    <li>This is a list item</li>
    <li>This is a list item</li>
</ul>

CSS 代码:

ul.noLeftMargin{
    margin:0px;
    padding:0px;
}

.noLeftMargin li{
    list-style-type:none;
}

希望这对您有所帮助。
