http://css-tricks.com/snippets/css/css-triangle/

i have following css -

.arrow_up {     width: 0;      height: 0;      border-left: 10px solid transparent;     border-right: 10px solid transparent;     border-bottom: 10px solid black;     position:absolute;     top:75px;     left:250px; }

and html -

<div class="arrow_up"></div>

output -

enter image description here

you can see right hand side border of arrow not smooth - there little cut. how can resolve it?

you need use pseudo element , rotate it: demo

css:

.arrow_up {     width: 100px;      height: 50px;      position:absolute;     top:150px;     left:250px;     overflow:hidden;/* hide part of pseudo overflowing*/ } .arrow_up:before {     content:'';     position:absolute;     width:100%;     padding-top:100%;/* draw square , change value other degrees angles*/     transform:rotate(45deg);/* we'll see corner */     background:black;     top:20px;/* tune according size of parent or size seen */ }

do not forget add vendor-prefix or use script adds them automaticly.

the use o pseudo element allows add content in box : ie. http://codepen.io/gc-nomade/pen/gdoga
