How to mark up a layout blocks with the CSS property “display:flex;”?

Question

In one of the project decided to use the new CSS property "display:flex;". After reading many articles and did not understand whether it is possible to make such a layout blocks without violating HTML code.

See image:

 .container { width:910px; display:flex; } figure { position:relative; width:300px; height:180px; } figure:first-child { width:600px; height:370px; } figure:first-child figcaption { width:590px; } figure figcaption { position:absolute; z-index:10; bottom:0; left:0; padding:5px; width:290px; background-color:rgba(0,0,0,.3); } 

 <div class="container"> <figure> <img src="http://placehold.it/600x370" alt=""> <figcaption>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</figcaption> </figure> <figure> <img src="http://placehold.it/300x180" alt=""> <figcaption>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</figcaption> </figure> <figure> <img src="http://placehold.it/300x180" alt=""> <figcaption>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</figcaption> </figure> </div> 

Also there is a ready code on JSFiddle

Sorry for my English.
