HTML5/CSS จัดเรียงตรงกลาง Align “center” ที่หายไป

HTML5 ไม่มี align=”center” ให้ใช้

เวลาที่ต้องการจัดเรียง Element ให้อยู่กึ่งกลางให้ใช้ CSS แทน ดังนี้

[code lang=”css”]
style="margin:auto; display:block;"
[/code]

หรือเพิ่มดังนี้

[code lang=”css”]
style="margin:auto; display:block; text-align:center;"
[/code]
