Form button and Browser

When you place a

inside a tag, the browser's default behavior can be confusing because of the HTML structure and how browsers interpret the elements. Let's break this down step by step.

Default Behavior of Tag
The element has a default type of submit, meaning that when it is clicked, it will attempt to submit the form in which it is contained.
When you place a inside a , the form is still recognized as a form, and the element inside it can still trigger form submission.
What Happens When You Put Inside ?
Incorrect HTML Structure:

Technically, putting a

inside a is not valid HTML according to the HTML specification. A cannot contain a because the tag is a form control element and is not allowed to contain interactive content like forms. However, some browsers might still render and function in a way that seems to work, but this is non-standard and can lead to unpredictable behavior.
Form Submission:

When you click the button, it triggers a form submission due to its type="submit" behavior. This will cause the form data to be sent to the server or the URL defined in the form's action attribute (if any).
Potential Issues:

Invalid HTML: As mentioned earlier, placing a

inside a is invalid HTML, and some browsers may not handle it correctly.
Unexpected Behavior: Different browsers may behave differently. Some browsers might ignore the invalid structure, while others could throw an error or fail to submit the form properly.
Correct HTML Structure
The correct approach is to separate the and the elements properly. The should be inside the , not the other way around. Here’s how you should structure it: Submit

Explanation:
The tag inside the form will trigger form submission when clicked (because of type="submit").
The form will submit the data in the form fields to the server when the button is clicked.
Why is this Important?
HTML Validation: Following the correct HTML structure ensures that your code adheres to standards and works across all browsers.
Predictable Behavior: Using the correct form structure allows you to ensure that your form behaves consistently and reliably.
Conclusion:
While placing a inside a may seem to work in some cases due to browser quirks, it is invalid HTML and can lead to unpredictable behavior. The correct approach is to place the inside the tag to ensure proper form submission and maintain valid, standards-compliant HTML.
