Bug 259428

text-decoration is a short hand value that allows you to set <'text-decoration-line'> || <'text-decoration-style'> || <'text-decoration-color'> [0]. Currently Safari only supports setting one value. See this example: <p id="one"> Hello World </p> <p id="two"> Hello World </p> <p id="three"> Hello World </p> <p id="four"> Hello World </p> #one { text-decoration: underline; } #two { text-decoration: blue wavy underline; } #three { text-decoration: overline red; } #four { text-decoration-color: blue; text-decoration-style: wavy; text-decoration-line: underline; } This example works properly in Chrome and Firefox.
