HTML style guide
Buttons
Button type
Button tags requires a type
attribute according to the W3C HTML specification.
// bad
<button></button>
// good
<button type="button"></button>
Button role
If an HTML element has an onClick
handler but is not a button, it should have role="button"
. This is more accessible.
// bad
<div onClick="doSomething"></div>
// good
<div role="button" onClick="doSomething"></div>
Links
Blank target
Use rel="noopener noreferrer"
whenever your links open in a new window, i.e. target="_blank"
. This prevents a security vulnerability documented by JitBit.
// bad
<a href="url" target="_blank"></a>
// good
<a href="url" target="_blank" rel="noopener noreferrer"></a>
Fake links
Do not use fake links. Use a button tag if a link only invokes JavaScript click event handlers, which is more semantic.
// bad
<a class="js-do-something" href="#"></a>
// good
<button class="js-do-something" type="button"></button>
