Question

如何将“星期日”日期列设置为红色。虽然使用colgroup只能更改背景颜色，但如何更改一列的日期颜色，即星期日。例如：如果我们在今天的日期谈话，那么用红色改变日期'4'，'11'，'18'，'25'的颜色。请帮忙......谢谢

Answer 1

试试这个

  for ($i=0; $i<($totle_day+$startday); $i++)
     {

       if(($i % 7) == 0 )

             echo "<tr>";

       if($i < $startday)

            echo "<td></td>";

       else if(($i % 7) == 0 )

            echo "<td align='center' style='color:red;' >". ($i - $startday +1) . "</td>";

       else 

        echo "<td align='center' >". ($i - $startday +1) . "</td>";


       if(($i % 7) == 6 )

            echo "</tr>";
    }

Answer 2

试试这个

为第一列提供类似sunday的类名称，并为sunday类提供所需的样式。

例如

变化

echo "<td align='center' >". ($i - $startday +1) . "</td>";

到

if($i % 7 == 0)
   echo "<td align='center' class='sunday'>". ($i - $startday +1) . "</td>";
else
    echo "<td align='center' >". ($i - $startday +1) . "</td>";

在css样式表中添加此

.sunday
{
color:red;
}

方法2：

使用此功能可以使其更简单。给表格一个id weeks

并在样式表中添加此

#weeks td:first-child {color: red; }

更改任何特定日期列的日期颜色？
