IMAGES_RESIZING and IMAGES_SPECIFY_SIZE
Related best practices:
[IMAGES_RESIZING]
Resize images at the server, if they have an intrinsic size.
[IMAGES_SPECIFY_SIZE]
Specify the size of images in markup, if they have an intrinsic size.
the height or width specified is less than the correseponding dimension of the image
… <img alt="" height="1" src="etusivu.gif" style="display: none;" width="1"/>… <img alt="" height="1" src="sub-etusivu.jpg" style="display: none;" width="1"/>… <img alt="TKK" border="0" src="../style/images/logo.gif"/>… <img align="left" alt="" border="" src="../style/images/logo-bw.gif"/>
Related best practice:
[MEASURES]
Do not use pixel measures and do not use absolute units in markup language attribute values and style sheet property values.
A length property uses an absolute unit
… font-size: 14px… font-size: 20px… font-size: 18px… font-size: 16px… min-height: 102px… height: 102px… background:transparent url(/sv/sub-etusivu.jpg) no-repeat 194px … width:465px… height:178px
Related best practice:
[OBJECTS_OR_SCRIPT]
Do not rely on embedded objects or script.
A "javascript:" link is used
… <a href="javascript:window.print();">Print</a>… <script src="../midcom-static/jQuery/jquery-1.2.1.js" type="text/javascript"/>… <script type="text/javascript">
var $j = jQuery.noConflict();
var MIDCOM_STATIC_URL = '/midcom-static';
var MIDCOM_PAGE_PREFIX = 'http://www.tkk.fi/';
</script>
Related best practice:

The total size of the page (89213 bytes) exceeds 20 kilobytes (Primary document: 8679, Images: 79407, Style sheets: 1127)
The HTTP status code is 404 or 5xx (in response to the resource
http://www.tkk.fi/images/logo-bw.gif) and the response relates to a
request for an included resource
Following tests were passed but raised one or more warnings.
You may want to consider if these warnings can help improve the page even further.
DEFAULT_INPUT_MODE
Related best practice:
[DEFAULT_INPUT_MODE]
Specify a default text entry mode, language and/or input format, if the device is known to support it.
There is no inputmode attribute on this text entry element
… <input id="search" name="q" type="text" value=""/>
Related best practice:
[STYLE_SHEETS_SUPPORT]
Organize documents so that if necessary they may be read without style sheets.
The CSS style sheet contains rules referencing the position, display or float properties
… display: none… display: block… float: left… float: right… display: block… float: left… display: none !important… display: none… display: none… display: none… display: none… display: none
Related best practice:
[STYLE_SHEETS_USE]
Use style sheets to control layout and presentation, unless the device is known not to support them.
All styles are restricted to CSS media types other than "handheld" or "all"
… <style media="print, handheld" type="text/css">
@import "/style/css/print.css";
</style>… <style media="screen, projection" type="text/css">
@import "/style/css/screen.css";
</style>… <img alt="" height="1" src="etusivu.gif" style="display: none;" width="1"/>… <img alt="" height="1" src="sub-etusivu.jpg" style="display: none;" width="1"/>… <table border="0" style="width:465px;height:178px;"><!-- ...skipped by mobileOK checker... ---></table>
Related best practice:
[TABLES_ALTERNATIVES]
Where possible, use an alternative to tabular presentation.
A Table element exists
… <table border="0" style="width:465px;height:178px;"><tbody><tr><!-- ...skipped by mobileOK checker... ---></tr><tr><!-- ...skipped by mobileOK checker... ---></tr><tr><!-- ...skipped by mobileOK checker... ---></tr><tr><!-- ...skipped by mobileOK checker... ---></tr><tr><!-- ...skipped by mobileOK checker... ---></tr><tr><!-- ...skipped by mobileOK checker... ---></tr><tr><!-- ...skipped by mobileOK checker... ---></tr><tr><!-- ...skipped by mobileOK checker... ---></tr><tr><!-- ...skipped by mobileOK checker... ---></tr></tbody></table>Some of the links on the page point to resources that may not work adequately on a mobile device:
Links to resources of which the declared character encoding is not UTF-8: NB: this service is released as a beta demonstrator of what the W3C MobileOK Basic checker service will look like; it is very likely to time out on some sites, esp. if they use a great number of links.
