I studied about hyperlink,images, videos, embed(iframe) and Tables. In tables I learnt about things like heading, columns, rows, border,border-collapse,rowspan and colspan.
I'm attaching the link for Tables here for your reference.
I'm sharing my today's work here.
I was just so engorssed in web development that I did not pay heed to the time so I only solved 1 problem of "Game of 2 stacks" on HacerRank.
