Finally, in order to make sure that the principal writing mode is indeed 'vertical-lr', the test checks that a simple text is affected by 'text-orientation: upright' since 'text-orientation: upright' should have a 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: sideways-lr; 36 } 37 38 html::after 39 { 40 content: "This text must be vertical, with letters upright."; 41 text-orientation: upright; 42 /* 'text-orientation: upright' has no effect with 'sideways-lr', but does with 'vertical-lr' */ 43 margin-top: 8px; 44 } 45 46 body 47 { 48 writing-mode: vertical-lr; 49 } 50 51 div 52 { 53 background-color: orange; 54 height: 100px; 55 width: 100px; 56 } 57 </style> 58 59 <body> 60 61 <div></div> 62 63 <p><img src="support/wm-propagation-body-003-exp-res.png" width="340" height="37" alt="Image download support must be enabled"> 64 65 <!-- 66 The image says: 67 Test passes if there is an orange square 68 in the <strong>upper-left corner</strong> of the page. 69 -->
