از آنجا که این اطلاعات (متا) خیلی زیاد هستند، برای آنها استانداردهای مختلفی تعیین و وضع شده است. و شما نمیتوانید از هر کلمهای در بخش اطلاعات متا استفاده کنید. لیستی که در ادامه میآید اطلاعات استانداردی است که شمامیتوانید دربخش متا تگهای html برای صفحات خود استفاده کنید.
در کل برای صفحات html (منظور از صفحات html کلا صفحات وب است، چرا که نهایتا همه زبانهای مختلف در مرورگر بصورت html رندر میشوند) دو نوع meta تگ داریم.
HTTP-EQUIV (HTTP header) Index : که اطلاعاتی در ارتباط با header صفحه در اختیار میگذارد و از دو بخش http-equiv و content تشکیل شده است.
NAME tag Index : که اطلاعاتی در ارتباط با صفحه و محتوای درونیاش در اختیار میگذارد و از دو بخش name و content تشکیل شده است.
شاید معروفترین متا تگها و پر استفادهترین آنها برای صفحات وب ۳ متا تگ
1 |
< meta http-equiv = "content-type" content = "text/html; charset=utf-8" /> |
2 |
< meta name = "keywords" content = "" /> |
3 |
< meta name = "description" content = "" /> |
باشند.
همانطور که ملاحظه میکنید، اولین خط از نوع اول و دو خط بعدی ازنوع دوم هستند. در زیر لیست مرجعی از اطلاعات متایی را که میتوانید به صفحات وبتان اضافه کنید میآورم. ذکراین نکته هم ضروری است که این اطلاعات باید در بخش قرار بگیرند.
فهرست زیر مربوط است به نوع اول بنابراین برای اضافه کردن هر کدام از آنها باید یک خط
1 |
< meta http-equiv = "" content=" /> |
به صفحه اضافه کنید. از فهرست زیر، آنچه را که در بخش Attribute آمده در داخل قسمت http-equiv قرار بدهید و آنچه را که در قسمت Source آمده (مطالعه کرده) و راه حل ارائه شده را در قسمت content بیاورید
