Some html tags not working
Hi,
I want to create a newsletter subscribe form on my webpage.
<form method="post" name="subscribeform" id="subscribeform" enctype="multipart/form-data">
<div class="input-group">
<input type="text" name="email" value="Newsletter Abo" id="email" class="form-control"><input type=hidden name="htmlemail" value="1"> <input type="hidden" name="list[11]" value="signup" /> <input type="hidden" name="subscribe" value="subscribe"/>
<div class="input-group-append">
<button type="button" class="btn btn-secondary" onclick="if (checkform()) {submitForm();} return false;" ><i class="fa fa-send"></i></button>
</div>
</div>
</form>
When I create a post with html formatting, the following tags are removed
<style>
<script>
<input>
<form>
How can I add this tags to my website?
