Some useful HTML tricks you should know.
A Thread 🧵👇
➡️Multiple: Using multiple attribute specifies that the user is allowed to enter/select more than one value.
It is valid for type email and file only.
➡️Document Refresh: The http-equiv attribute can be used to simulate an HTTP response header.
By using the refresh property, a document can be refreshed automatically after mentioned time.
➡️Optgroup: Use the <optgroup> element to create a grouping of options within a <select> element.
➡️Abbr Tag: The <abbr> tag defines an abbreviation or an acronym, like "HTML", "CSS", "ASAP", "ATM".
➡️ Poster: Use the `poster` attribute to specify an image to be shown while the video is downloading, or until the user hits the play button.
If this image is not set then it will take the first frame of the video as a poster image.
