Create responsive triangle with text

Question

I need to created a responsive triangle using css and html. The triangle will comprise of text and as the text would increase I want the size of triangle to also increase.

Below is the fiddle which I have created.

fiddle

<div class="wrapper">
    <div class="top-layer-content banner-notch"></div>
    <a class="icon-play fa fa-play-circle-o" rel="lightbox" href="#">
        <p> See it in action</p>
    </a>
<div>

.wrapper{
    position:relative;
}
.banner-notch {
    width: 0;
    height: 0;
    border-bottom: 220px solid #000;
    border-left: 220px solid transparent;
    filter: alpha(opacity=50);
    opacity: 0.6;
    color:white;
    position:relative;
    float:right;
}

.wrapper a{
    position:absolute;
    top:130px;
    right:20px;
    color:white;
    text-decoration:none;
    font-size:25px;
    background-position:0 50px;
}

.wrapper .fa-play-circle-o:before{
    padding-left:38px;
}

.wrapper p{
    font-size:16px;
}

I checked the follow links but it seems the triangle shape is different and the text does not seem to wrap. Text starts overflowing.

Answer 1

You can use pseudo elements and transform:rotate() to make a triangle that adapts to the size of its content.

FIDDLE

This technique might need a bit of tweaking according to the context you use it in (container with to traingle width ratio) and the design you want when text becomes larger.

HTML:

<div class="wrapper">
    <a class="icon-play fa fa-play-circle-o" rel="lightbox" href="#">
        <p> See it in action</p>
    </a>
</div>

CSS:

.wrapper{
    position: relative;
    float:right;
    clear:right;
    overflow:hidden;
    z-index:1;
    padding:0 1% 0 30%;
    margin-right:5%;
}
.fa-play-circle-o{
    display:block;
    margin:130% 0 2%;
    color:#fff;
    text-decoration:none;
    font-size:18px;
    text-align:center;
}
.fa-play-circle-o:before{
    font-size:30px;
}

.wrapper:after{
    content:"";
    position:absolute;
    background-color:#666666;
    width:500%;
    height:100%;
    top:0;right:0;
    z-index:-1;

    -ms-transform: rotate(-45deg);
    -webkit-transform: rotate(-45deg);
    transform: rotate(-45deg);

    -ms-transform-origin:100% 0;
    -webkit-transform-origin:100% 0;
    transform-origin:100% 0;    
}

Answer 2

I think it is possible using just CSS Gradient. As I am not good with gradients, I used online CSS gradient generator and did the following:

CSS

.triangle {
    width: 300px;
    border: 1px solid black;
    background-image: -webkit-gradient(linear, left top, left top, color-stop(0, #000000), color-stop(0.5, #FFFFFF));
    background-image: -o-linear-gradient(left top, #000000 0%, #FFFFFF 50%);
    background-image: -moz-linear-gradient(left top, #000000 0%, #FFFFFF 50%);
    background-image: -webkit-linear-gradient(left top, #000000 0%, #FFFFFF 50%);
    background-image: -ms-linear-gradient(left top, #000000 0%, #FFFFFF 50%);
    background-image: linear-gradient(to left top, #000000 0%, #FFFFFF 50%);
}
