Answer 1

Important to note that there is a set of supported HTML tags that you can use when developing visualforce pages available here along with attributes.

You will also want to go through the list of Standard Components Reference available here if you will be developing in Salesforce.

If you read carefully, you will notice that:

<Input type="Text"/>

Is not supported.

Last but not least, the H&T Portal is a great reference source for searching prior to asking.

Answer 2

You should use input field here as you are using StandardController without any extensions. Refer apex:inputField

An HTML input element for a value that corresponds to a field on a Salesforce object. The component respects the attributes of the associated field, including whether the field is required or unique, and the user interface widget to display to get input from the user. For example, if the specified component is a date field, a calendar input widget is displayed. When used in an , tags automatically display with their corresponding output label.

<apex:page docType="HTML-5.0" 
           standardController="Account"
           standardStylesheets="false"
           showheader="false"
           sidebar="false">
<apex:form >
<tr>
<td>
Account Name:
</td>
<td>
<apex:inputField value="{!Account.Name}"/> 
</td>
</tr>

<apex:commandButton action="{!Save}"
                    value="Save" />
