I am using Magento 2.2.2

I have one form on my website with the fields "Name" and "Email". Now when the customer submits the form I want to send an email to the email address filled by the customer.

I want to send custom HTML in this email and this HTML includes images. How can I achieve this?

I have used below code:

```
<form class="form"  method="post" name="form_1" id="form_1" enctype="multipart/form-data">

    <div class="formdiv">
        <h2>Custom Form</h2>
    </div>

    <label>Name</label>
    <input type="text" id="name" name="name" required="required" placeholder="Enter Your Name" />

    <label>Email</label>
    <input type="email" id="email_share" name="email_share" required="required" placeholder="Enter Your Email" />

    <input type="submit" id="submit_result" name="submit_result" value="Submit">
</form>
<?php
if(isset($_POST['submit_result']))
{

$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 
$to = "test@gmail.com";
$nameTo = $_POST['txtname'];
$transport = $objectManager->create('Magento\Framework\Mail\Template\TransportBuilder'); 
$data = $transport
    ->setTemplateIdentifier(7)
    ->setTemplateOptions(['area' => \Magento\Framework\App\Area::AREA_FRONTEND, 'store' => 1])
    ->setFrom(['name' => 'Test','email' => 'test1@gmail.com'])
    ->addTo($to,$nameTo)
    ->getTransport();
$data->sendMessage();

}
?>

```

And below as well:

```
<form class="form"  method="post" name="form_1" id="form_1" enctype="multipart/form-data">

    <div class="formdiv">
        <h2>Custom Form</h2>
    </div>

    <label>Name</label>
    <input type="text" id="name" name="name" required="required" placeholder="Enter Your Name" />

    <label>Email</label>
    <input type="email" id="email_share" name="email_share" required="required" placeholder="Enter Your Email" />

    <input type="submit" id="submit_result" name="submit_result" value="Submit">
</form>
<?php
if(isset($_POST['submit_result']))
{

$to = "test1@gmail.com";
$nameTo = $_POST['txtname'];
$from = "test@gmail.com";
$nameFrom = "test";

$body ="<table cellpadding='4' cellspacing='0' style='border-collapse:collapse' width='500' border='1'>";
$body.="<tr><td align='left' colspan='2' style='background:#CCC;'><strong>Test email</strong></td></tr>";
$body.="<tr><td width='150' align='left'>Name</td><td align='left'>".$_POST['name']."</td></tr>";
$body.="<tr><td width='150' align='left'>Email</td><td align='left'>".$_POST['email_share']."<br /></td></tr>"; 
$body.="</table>";

$email = new \Zend_Mail();
$email->setSubject("Test Request");
$email->setBodyHtml($body); 
$email->setFrom($from, $nameFrom);
$email->addTo($to, $nameTo);
$email->send();     

}
?>

```

I have tried both logics but they are not working
