I made the following code but the two DIV blocks have a blank space between them.
<!DOCTYPE html>
<html>
<body>
<div style="background:blue; width: 200px; height: 200px">
<p>123</p>
</div>
<div style="background: yellow; width: 200px; height: 200px">
<p>456</p>
</div>
</body>
</html>
I would like to have a code where there is no space between the two blocks. How do I do that?
