If your textarea
have a static width you can use combination of non-breaking space and automatic textarea wrapping. Just replace spaces to nbsp for every line and make sure that two neighbour lines can't fit into one. In practice line length > cols/2
.
This isn't the best way, but could be the only cross-browser solution.
<textarea class="textAreaMultiligne" _x000D_
placeholder="Hello, This is multiligne example Have Fun "_x000D_
rows="5" cols="35"></textarea>
_x000D_
