CSS margin – right and margin – left properties can be used in HTML5 to center the blocks as per one’s requirements.

<!DOCTYPE HTML> <html> <head> <title> Center text</title> </head> <body> <p style="text-align: center">Hello World!</p> </body> </html> 

Centering a block using CSS margin alignment property
