The <thead> tag is used to group header content in an HTML table. It is used in conjunction with the "tbody> and "tfoot" elements to specify each part of a table (header, body, footer). Browsers can use these elements to enable scrolling of the table body independently of the header and footer. Also, when printing a large table that spans multiple pages, these elements can enable the table header and footer to be printed at the top and bottom of each page.
The "thead" element must have one or more "tr" tags inside. The "thead" tag must be used in the following context: as a child of a "table" element, after any "caption" and "colgroup" elements, and before any "tbody", "tfoot", and "tr" elements. The "thead", "tbody", and "tfoot" elements will not affect the layout of the table by default.
However, you can use CSS to style these elements!
