我对css不是很擅长,但我有以下两种形式:
    //below is where it displays course name
        $outputcourse = ""; 
        $outputcourse .= "<p><strong>Course:</strong> " . $course .  " - "  . $coursename . "</p>";
    //below is where it displays module name
    $outputmodule = ""; 
    $outputmodule = sprintf("<p><strong>Module:</strong> %s - %s</p>", $moduleId, $moduleName);
    //below is form where it displays assessments drop down menu
        $assessmentform = "<form action='".htmlentities($_SERVER['PHP_SELF'])."' method='post'>
<p>{$outputcourse}</p>
<p>{$outputmodule}</p>
        <p><strong>Assessments:</strong> {$sessionHTML} </p>   
        </form>";
        echo $assessmentform;
        }
        //below is form where it displays all of the text inputs and submit button
        $editsession = "<form id='updateForm'>
            <p><strong>Current Assessment's Date/Start Time:</strong></p>
            <table>
            <tr>
            <th>Assessment:</th>
            <td><input type='text' id='currentAssessment' name='Assessmentcurrent' readonly='readonly' value='' /> </td>
            </tr>
            <tr>
            <th>Date:</th>
            <td><input type='text' id='currentDate' name='Datecurrent' readonly='readonly' value='' /> </td>
            </tr>
            <tr>
            <th>Start Time:</th>
            <td><input type='text' id='currentTime' name='Timecurrent' readonly='readonly' value=''/> </td>
            </tr>
            </table>
            <div id='currentAlert'></div>
            <p><strong>New Assessment's Date/Start Time:</strong></p>
            <table>
            <tr>
            <th>Assessment:</th>
            <td><input type='text' id='newAssessment' name='Assessmentnew' readonly='readonly' value='' /> </td>
            </tr>
            <tr>
            <th>Date:</th> 
            <td><input type='text' id='newDate' name='Datenew' readonly='readonly' value='' /> </td>
            </tr>
            <tr>
            <th>Start Time:</th> 
            <td><input type='text' id='newTime' name='Timenew' readonly='readonly' value=''/><span class='timepicker_button_trigger'><img src='Images/clock.gif' alt='Choose Time' /></span> </td>
            </tr>
            </table>
            <div id='datetimeAlert'></div>
            </form>
            <p><button id='updateSubmit'>Update Date/Start Time</button></p>
            <div id='targetdiv'></div>
        ";
        echo $editsession;
CSS:
form#assessmentForm {
 float: left; 
 border: 1px solid red;
}
form#updateForm {
 float:left;
 clear: right;
 /* with some space to the left of the second form */
 margin-right: 100px; 
}
p#submitupdatebtn {
  clear: both;
}
目前,两种形式都显示在彼此之上。我真正想做的是显示$editsession表单,显示$assessmentform在右侧表单旁边,两个表单之间有一点空间。
如何做到这一点?我希望它适用于所有主要浏览器。
下面显示了合并在一起的两个屏幕截图,以显示我希望它如何显示:

谢谢
