These widgets can be allowed to be resized on some platforms but not others. We'll account for that by giving them height: 100% in the reference case, so that if they're allowed to stretch, then they'll stretch in both the reference case and the testcase. --> <html> <head> <style> div.flexbox { display: flex; background: lightgray; float: left; height: 60px; margin-right: 10px; } div.flexbox > * { outline: 1px dashed black; margin: 0; vertical-align: top; height: auto; align-self: stretch; } br { clear: left; } </style> </head> <body> <div class="flexbox"><input type="button"></div> <div class="flexbox"><input type="checkbox"></div> <br> <div class="flexbox"><input type="image"></div> <div class="flexbox"><input type="radio"></div> <br> <div class="flexbox"><input type="reset"></div> <div class="flexbox"><input type="submit"></div> </body> </html>
