问题
I got this error when validating my page with w3c's validator.
Source:
<form action="form.php" method="post">
<input type="text"/>
</form>
Can someone show me why I may have gotten this error? Thanks in advance!

This answer applies to XHTML, not HTML5.
The form and body element only accept block level children
<form action="/"> <input type="submit"> </form>
… will produce the error:document type does not allow element "input" here; missing one of "p", "h1", "h2", "h3", "h4", "h5", "h6", "div", "pre", "address", "fieldset", "ins", "del" start-tag.
In Strict variants of (X)HTML, a form element may have only block elements as its children, but form controls (such as input elements) are inline elements. The solution is to pick a block element with appropriate semantics that may contain inline elements; helpfully the validator produces a list that can help you narrow it down.
When it comes to a form, appropriate elements are usually fieldset or a plain div.

So doing something like
<form action="form.php" method="post">
<fieldset>
<input type="text"/>
</fieldset>
</form>
will solve your problem.
