Web page HTML form

Today, I first learned about image hotspots and embedded other pages in the original page.
Image hotspot:
<map name= "Ditu";
<area shape= "rect" coords= " 196,92,296,192 "href=" http://www.baidu.com "/>
</map>
Embed other pages in the original page:
<iframe src=" Address of other pages " Width= "" height= "" frameborder= "0" scrolling= "0";
</iframe>
Next, I learned the key elements of this section-form, <form></ Form>. The form consists of three types: text input, button, and select Input.
1. Text Input
text box <input type= "text"/>
Password box <input type= "password"/>
Text field <textarea cols= "rows=" "></TEXTAREA>
2. Button
Submit button <input type=" Submit "value=" commit "/>
Reset button <input type=" Reset "value= "Reset"/>
Normal button <input type= "button" value= ""/>
Picture button <input type= "image" src= "picture Address"/>
3. Select Input
radio button Group <input type= "Redio" name= "/>
check box group <input type=" checkbox "/>
drop-down list box
<select size=" 1 ">
<option> content 1</option>
<option> content 2</option>
<option> content 3</option>
</select>
