html - Is it OK to style anchor tags as block elements? -

is ok use html below style anchor block element? read somewhere before it's wrong, can't see why , it's damn convenient! drawbacks of method, if any?

<style> a.button{ display:inline-block; padding: 10px 20px; border: 1px solid grey; } </style>  <a class="button" href="#link">click me!</a> 

not ok <a> elements styled blocks or inline-blocks, it's necessary in cases, avoid problems.
take bit of code:

a {outline:1px dotted}

click <a href="#"><div>here</div></a>

in browsers, outline around anchor not proper rectangular shape, because of div inside. in others, outline isn't there @ all. if change a's display block, differences go away; has nice rectangular outline in browsers.

a {outline:1px dotted; display:block}

click <a href="#"><div>here</div></a>

so, no need worry.
