The <meter> HTML element represents either a scalar value within a known range or a fractional value.This is also known as a gauge.
Examples: disk usage, the relevance of a query result, etc. The <meter> tag should not be used to indicate progress (as in a progress bar). For progress bars, use the <progress> tag. Always add the <label> tag for best accessibility practices.
By default, the <meter> background is green and gray. With CSS the background color can be customized.
The <meter> tag is not supported in Edge 12 (or earlier).
