 ## HTML Form
 
-## Meta tags
+A form is one part of a website. Different websites handle user data using a HTML form. For instance, when we create an account or sign in to our account we fill an input field. Filling a form on a website is a common activity. Therefore, we have to know how to build a form.
+To create a form, we use _form_ element and the _form_ element wrap other input fields. The input field might be text, number, date, checkbox, radio button, file ,or others types.
+
+```html
+<form>
+  <label>First name:</label>
+  <input type="text" />
+  <input type="submit" value="Submit" />
+</form>
+```
+
+You can see the output of the above code here.
+
+<form>
+  <label>First name:</label>
+  <input type="text" />
+  <input type="submit" value="Submit" />
+</form>
+

+              <div>
+                <input type="submit" value="Submit" />
+              </div>
+            </form>
+</div>
+
+What is matters the most is understanding how the HTML form works, this is not an exhaustive list of all the input fields. Whenever you would like to solve some problem, try to search it on the internet using a key word. Searching is also one the most important skill in software development.
 
 # Day 9
 
 ## HTML Table
 
+In this section, we will see how to create an HTML table. Table has an external border, header rows and header cell, body rows and its cells and it could have also a footer row. To make an HTML table, we need a _table_ element that wrap all the rows and the rows wrap all the data cells.
+
+```html
+<table>
+  <tr>
+    <td>Name</td>
+    <td>Gender</td>
+    <td>Country</td>
+  </tr>
+  <tr>
+    <td>Asabeneh</td>
+    <td>250</td>
+    <td>Finland</td>
+  </tr>
+</table>
+```
+
+Let us see the output of the above code
+
+<table>
+  <tr>
+    <td>Name</td>
+    <td>Gender</td>
+    <td>Country</td>
+  </tr>
+  <tr>
+  <td>Asabeneh</td>
+  <td>250</td>
+  <td>Finland</td>
+  </tr>
+</table>
+However, HTML table has thead, tbody and tfooter. Let us add thead and tbody to the above code. In addition, we can use th in the table head instead to td to make the table heading bold.
+
+```html
+<table>
+  <thead>
+    <tr>
+      <th>Name</th>
+      <th>Gender</th>
+      <th>Country</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>Asabeneh</td>
+      <td>250</td>
+      <td>Finland</td>
+    </tr>
+  </tbody>
+</table>
+```
+
+The out for the above code
+
+<table>
+  <thead>
+    <tr>
+      <th>Name</th>
+      <th>Gender</th>
+      <th>Country</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>Asabeneh</td>
+      <td>250</td>
+      <td>Finland</td>
+    </tr>
+  </tbody>
+</table>

+The author of this challenge creates different challenges every year. Let us put all his challenges on a table.
