Finally, in order to make sure that the principal writing mode is indeed 'sideways-rl', the test checks that a simple text is not affected by 'text-orientation: upright' since 'text-orientation: upright' should have no impact and no rendering effect on it."> 17 18 <!-- 19 Tests 032 to 035: html's writing-mode is not specified 20 21 Tests 036 to 039: html's writing-mode is specified as horizontal-tb 22 23 Tests 040 to 043: html's writing-mode is specified as vertical-rl 24 25 Tests 044 to 047: html's writing-mode is specified as vertical-lr 26 27 Tests 048 to 051: html's writing-mode is specified as sideways-rl 28 29 Tests 052 to 055: html's writing-mode is specified as sideways-lr 30 --> 31 32 <style> 33 html 34 { 35 writing-mode: vertical-rl; 36 } 37 38 html::after 39 { 40 content: "This text must be written sideways: vertically, with letters rotated 90 degrees."; 41 text-orientation: upright; 42 /* 'text-orientation: upright' has no effect with 'sideways-rl', but does with 'vertical-rl' */ 43 } 44 45 body 46 { 47 writing-mode: sideways-rl; 48 } 49 50 div 51 { 52 background-color: blue; 53 height: 100px; 54 width: 100px; 55 } 56 </style> 57 58 <body> 59 60 <div></div> 61 62 <p><img src="support/block-flow-direction-025-exp-res.png" width="359" height="36" alt="Image download support must be enabled"> 63 64 <!-- 65 The image says: 66 Test passes if there is a blue square in the 67 <strong>upper-right corner</strong> of the page. 68 -->
