在这个页面悬停不工作，我不知道为什么，脚也不采取100%的宽度，即使我已经给了它

in this page hover is not working i dont know why and also footer is not taking 100% width even though i have given to it

本文关键字：100% 悬停 工作 我不知道 为什么 | 更新日期: 2023-09-27

是我的编码不正确或什么是悬停和页脚的问题。我需要知道php邮件程序是正确的还是我有错误，我无法找到错误，因为邮件功能不工作在本地服务器。

<?php
if(isset($_POST["submit"])){
if($_POST["name"]==""||$_POST["email"]==""||$_POST["phone"]==""||$_POST["msg"]==""){
echo "Fill All Fields..";
}
else
{
$email=$_POST['email'];
$email= filter_var($email, FILTER_VALIDATE_EMAIL);
if (!$email){
echo "Invalid Sender's Email";
}
else{
$subject = $_POST['sub'];
$message = $_POST['msg'];
$headers = 'From:'. $email2 . "'r'n"; 
$headers .= 'Cc:'. $email2 . "'r'n";
$message = wordwrap($message, 70);
mail("recievers@gmail.com", $subject, $message, $headers);
echo "Your mail has been sent successfuly!";
}
}

您可以使用sendmail包从本地主机发送邮件，sendmail包是XAMPP内置的。因此，如果您正在使用XAMPP，那么您可以轻松地从本地主机发送邮件。

例如，您可以配置C:'xampp'php'php.ini和c:'xampp'sendmail'sendmail.ini为gmail发送邮件。

在C:'xampp'php'php.ini中找到extension=php_openssl.dll并删除该行开头的分号以使SSL适用于gmail for localhost

在php.ini文件中找到[mail function]并修改

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = my-gmail-id@gmail.com
sendmail_path = "'"C:'xampp'sendmail'sendmail.exe'" -t"
现在打开C:'xampp'sendmail'sendmail.ini。将sendmail.ini中的所有现有代码替换为以下代码 
[sendmail]
smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
auth_username=my-gmail-id@gmail.com
auth_password=my-gmail-password
force_sender=my-gmail-id@gmail.com

现在你已经完成了!!创建带有邮件功能的PHP文件，从本地主机发送邮件。

PS:不要忘记替换上面代码中的my-gmail-id和my-gmail-password。另外，如果从上面复制设置，不要忘记删除重复的键。例如，如果有另一个sendmail_path:

，请在行后面注释

sendmail_"路径= " C: ' xampp ' mailtodisk ' mailtodisk.exe "

php.ini文件

还要记住使用XAMMP控制面板重新启动服务器，以便更改生效。

或

XMail或hMailServer可以做到这一点。

或

尝试PHPMailer

悬停不工作

  • 这是因为carousel-inner是溢出在您的#navbardiv，所以使用overflow: hidden;

  • 页脚不占用100%!!因为footer是#wrapper的子类，所以100%只取父(#wrapper)宽度。因此，使用vw而不是%和计算margin-left属性将解决您的问题

    #navbar
{
height:60px;
width:100%;
background-color:black;
color:white;
overflow: hidden;
}
.footer
{
height:60px;
width: 100vw;
margin-left: calc(-51vw + 50%);
background-color:black;
padding:10px;
color:white;
position: fixed;
bottom: 0;
}
#con {
margin-bottom: 23vw;
}

页脚的原因不是100%。

  1. 是100%的，但在加入padding:10px;后，它变得超过100%。要解决这个问题，你必须做出选择。要么你使用width:100%;而不添加padding，要么你添加padding并使用display:block;而不是width:100%;
  2. 其次，box缺少闭合div。
你有

<div class="container-fluid text-center bg-grey"><!--boxes-->
  <div class="row text-center">
    <div class="col-sm-4">
      <div class="thumbnail">
        <img src="D:'task'photo'i.jpg" alt="Innovation">
        <p><strong>Innovation</strong></p>
      </div>
    </div>
    <div class="col-sm-4">
      <div class="thumbnail">
        <img src="D:'task'photo'cr.png" alt="Creative">
        <p><strong>Creativity</strong></p>
      </div>
    </div>
    <div class="col-sm-4">
      <div class="thumbnail">
        <img src="D:'task'photo'po.jpg" alt="Positive">
        <p><strong>Positivity</strong></p>
              </div>
        </div>
</div><!--end boxes-->

代替:

<div class="container-fluid text-center bg-grey"><!--boxes-->
  <div class="row text-center">
    <div class="col-sm-4">
      <div class="thumbnail">
        <img src="D:'task'photo'i.jpg" alt="Innovation">
        <p><strong>Innovation</strong></p>
      </div>
    </div>
    <div class="col-sm-4">
      <div class="thumbnail">
        <img src="D:'task'photo'cr.png" alt="Creative">
        <p><strong>Creativity</strong></p>
      </div>
    </div>
    <div class="col-sm-4">
      <div class="thumbnail">
        <img src="D:'task'photo'po.jpg" alt="Positive">
        <p><strong>Positivity</strong></p>
              </div>
                </div>
    </div><!-- this is the missing closing div-->
</div><!--end boxes-->
  • 最后。你必须把float:left;从页脚和使用clear:both;代替。这样做你会发现你有更好的结果。
