[Sonya S.]

Hi!
Please help my create e-mail form.
I am new to typo3. I have html and css for my e-mail form. I installed typo3 4.7 I didn't understand how to create a form on my html and css in typo3.
This is my html-code:

<!--  Mail form inserted: [begin] -->
<div id="forma-obrat-sv">
<div id="inputArea">
<form method="post" action="index.php" enctype="multipart/form-data">
<div id="m...a">
  ......
</div>  
<textarea rows="4" cols="30" placeholder="Text..." ></textarea>
<input type="text" placeholder="Name..." />
<input type="text" placeholder="E-mail..." />
<input type="text" placeholder="Web..." />
<input type="submit" class="button" value="#">  
</form>
</div>
</div>
<!--  Mail form inserted: [end] -->

thanks for the help...
