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?
