如果我使用 span-x 来定义元素宽度是不是错了?
<div class="search span-7 prepend-17 last">
<fieldset>
<form action="index.php" method="get">
<input type="hidden" name="page" value="found"/>
<input class="span-4" type="text" MAXLENGTH="25" placeholder="Enter text to search" name="search"/>
<input class="span-3 last" type="submit" value="search" />
</form>
</fieldset>
</div>
