div和类没有显示

Question

我在我的网站上测试条码，但由于某种原因，代表条码的class =“b128”的div没有出现。如果我在另一个网站上测试相同的源代码，它会显示，但具有不同的样式。

有谁知道我该如何让这个源代码出现，并保持原来的样式在同一时间？

<style> 
div.b128{ 
border-left: 1px black solid; 
height: 60px; 
} 
</style> 

<?php 
global $char128asc,$char128charWidth; 
$char128asc=' !"#$%&\'()*+,-./:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~';     
$char128wid = array(

Answer 1

您没有关闭大部分标签。试试这个：

$html = "<table cellpadding=0 cellspacing=0><tr>"; 
    for ($x = 0; $x < strlen($w); $x += 2)       // code 128 widths: black border, then white space 
     $html .= "<td><div class=\"b128\" style=\"border-left-width:{$w[$x]};width:{$w[$x+1]}\"></div></td>"; 
    return "$html</tr><tr><td colspan=" . strlen($w) . " align=center><font family=arial size=2><b>$text</b></font></td></tr></table>";
