Why after using div to add a small form, the entire page in the center will move a little to the left, and the same will happen after PHP searches the database and returns data_html/css_WEB-ITnose

I just learned PHP and made a message board. The whole page is centered. After adding the div form, the page moves to the left.
Please tell me how to solve it. My form is very small and cannot support the big page. I don’t know why the whole page moves to the left?
PHP searches the mysql database and returns the data. I put it in a table under the div (beginner) ...div and table are a bit confusing), the table also has a very small width, and the resulting page is the same as above, with the whole page moved a little to the left,

	<div style="margin-top:20px;margin-left:10px;">	<strong>发表留言</strong>( php新手,谢谢。)</div>	<div id=respond style="margin-top:10px;margin-left:10px;">		<form action="posted.php" method="post" id="commentform">			<input name="name" id="author" value="" type="text" /><br />			<input name="email" id="email" value="" type="text" /><br />			<input name="qq" id="url" value="" type="text" /><br />			<textarea name="info"></textarea><br />			<button type="submit" name="submit" id="submit">提交响应</button><button type="reset">重置</button>			</form>		</div>

Reply to the discussion (solution)

form{margin:0; padding:0}

form{margin:0; padding:0} After trying it, it still moved to the left as a whole

I found the reason. When the page exceeds the vertical length of the browser, it moves to the left. What should I do?

Because a scroll bar appears, just set: overflow-y:scroll in the body.

The method above solves this problem. You really need to learn basic css well.
