 ##  Available classes
 
 * The `.hidden-*-up` classes hide the element when the viewport is at the given breakpoint or wider. For example, `.hidden-md-up` hides an element on medium, large, and extra-large viewports.
-* The `.hidden-*-down` classes hide the element when the viewport is at the given breakpoint or smaller. For example, `.hidden-md-down` hides an element on extra-small, small, and medium viewports).
+* The `.hidden-*-down` classes hide the element when the viewport is at the given breakpoint or smaller. For example, `.hidden-md-down` hides an element on extra-small, small, and medium viewports.
 * There are no explicit "visible"/"show" responsive utility classes; you make an element visible by simply not hiding it at that breakpoint size.
 * You can combine one `.hidden-*-up` class with one `.hidden-*-down` class to show an element only on a given interval of screen sizes. For example, `.hidden-sm-down.hidden-xl-up` shows the element only on medium and large viewports. Using multiple `.hidden-*-up` classes or multiple `.hidden-*-down` classes is redundant and pointless.
 * These classes don't attempt to accommodate less common cases where an element's visibility can't be expressed as a single contiguous range of viewport breakpoint sizes; you will instead need to use custom CSS in such cases.
