Question

I am not very strong with css but what I have is 2 forms below:

    //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;
}

At the moment both form are displayed above one another. What I really want to do is display $editsession form to be displayed next to the $assessmentform form on the right hand side with a little space in between the two forms.

How can this be achieved? And I want this to work in all Major browsers.

Below shows two screenshots merged together to show how I want it to be displayed:

UPDATE:

Below is now what it is displaying:

You just need to float: left; the forms, and it is recommended to also clear: right; the second form, so that other floating elements don’t appear to the right of it. Finally, clear: both; on the <p> that follows the second form so no preceding element floats to the left or right of it.

form {
 /* Float both forms to the left */
 float: left; 
 /* borders added for visibility. Just remove them */
 border: 1px solid red;
}
form#updateForm {
 clear: right;
 /* with some space to the left of the second form */
 margin-right: 20px; 
}
/* Give an id to the <p> which follows the second form and clear: both */
p#submit {
  clear: both;
}

In your markup, give the <p> which follows the second form an id, so it can be easily targeted in the CSS

<p id='submit'><button id='updateSubmit'>Update Date/Start Time</button></p>

Then move it inside the preceding <form> tag, since it is a part of that form.

Here is a demonstration
