Bordo su un triangolo

Sto usando 2 bordi per fare questo triangolo e voglio avere un bordo come il riquadro sottostante ( border-bottom: 6px double black; border-right: 6px double black;) sul bordo appena inclinato del triangolo. La più grande difficoltà è il fatto che sia una leggera opacità.

> Bordo su un triangolo

.title { 
 
\t width: 300px; 
 
\t height: 0px; 
 
\t border-bottom: 50px solid #f2f2f2; 
 
\t border-right: 50px solid transparent; 
 
\t opacity: .8; 
 
\t position: absolute; 
 
\t margin: 47px 0 0 62px; 
 
} 
 
#media { 
 
\t margin: 97px 0 0 62px; 
 
\t position: absolute; 
 
\t height: 100px; 
 
\t background-color: #f2f2f2; 
 
\t opacity: .8; 
 
\t width: 350px; 
 
\t z-index: 2; 
 
\t border-bottom: 6px double black; 
 
\t border-right: 6px double black; 
 
}

per conferirgli l'uso di opacità: 'background: rbga (0, 0, 255, 0,7);' 'o l'opacità: 0,7;' // utilizzare valore RGB da abbinare il colore che intendi – warkentien2

ti posso dare due soluzioni. Primo (html + css) e secondo (html + css + svg).

Prima presenta i seguenti svantaggi:

una frontiera
Non reattivo disegno
necessario utilizzare solo riempimento solido background
Inflessibilità nelle impostazioni di colori e dimensioni

HTML

<div class="figure">some text</div>

CSS

 * { 
      font-size: 0; 
      margin: 0; 
      padding: 0; 
     } 

     body { 
      background-color: #5FC3B9; 
     } 

     /* The main figure */ 
     .figure { 
      display: block; 
      position: relative; 
      margin: 100px auto; 
      padding: 12px; 
      opacity: .8; 
      width: 356px; 
      height: 131px; 
      font: 16px/24px sans-serif; 
      background-color: #eee; 
      color: black; 
      border-bottom: 2px solid #333; 
      border-right: 2px solid #333; 
     } 

     /* Triangles - grey and white */ 
     .figure:after, 
     .figure:before { 
      display: inline-block; 
      position: absolute; 
      top:0; 
      right: 0; 
      border-left: 51px solid transparent; 
      border-top: 51px solid #333; 
      content: ''; 
      z-index: 100; 
     } 

     /* Styling for second triangle [WHITE] */ 

     .figure:before { 
      border-left: 50px solid transparent; 
      border-top: 50px solid transparent; 
      border-top-color: #5FC3B9; 
      right: -2px; 
      z-index: 200; 
     }

Seconda

HTML + SVG

body{ 
 
    background-image: url("http://www.favewallpapers.com/pic/201409/2560x1600/favewallpapers.com-6863.jpg"); 
 
    background-attachment: fixed; 
 
    background-position: center; 
 
    background-size: cover; 
 
}
