Question

Consistently adjusting the size of a <textarea> across various browsers such as IE, FF, Safari, and

My <textarea> needs to fit into a space that is a percentage of the screen size, but I'm encountering some issues with different browsers. In FireFox, I am able to achieve good results by setting the CSS properties as follows:

#container { width: 70%; height:70% }
#text_area { width: 100%; height: 100%; margin: 0; padding:0; }

However, in IE 6 and 7, I am experiencing odd behavior. In IE6, the textbox seems to have padding on both the left and right sides, causing my container to expand. In IE7, the padding is only on the left side, but the right edge of the textbox extends beyond the container.

The height setting does not seem to work in either IE6 or IE7; the <textarea> remains just 2 rows tall, ignoring the height:100% directive.

Is there a consistent way to size a <textarea> across all browsers?

And is there a method to eliminate the left-padding on the <textarea>?

Update

After trying position:absolute, I was able to remove the left padding, but the width still presents an issue. IE7 calculates the 100% width incorrectly, causing the <textarea> to spill out of its containing <div>.

If time permits, I will create a separate example to illustrate this further...

In my experience, I have encountered a similar issue with ASP.Net textbox controls in IE7. It was causing the entire content section to overflow into neighboring sections due to the textbox width being set to "100%". While I can't recall where I originally found the solution, credit goes to whoever discovered it.

To resolve this issue, I ended up wrapping the asp:Textbox inside its own table and applying the properties "table-layout: fixed; width: 100%" to the table, and "position: relative; width: 100%;" to the textbox/textarea. The code structure looked like this:

<table style="width: 100%; table-layout: fixed;">
  <tbody>
    <tr>
     <td>
      <asp:Textbox id="txtMyTextbox" runat="server" Width="100%" style="position: relative;"/>
     </td>
    </tr>
   </tbody>
 </table>

Although it may not be the most elegant solution, I can confirm that it did resolve the issue across all browsers. For more information on this problem, you can check out my write-up HERE.

I hope this explanation proves helpful.

Perhaps there is a clever CSS technique that can accomplish this task, but from my own experience, using Javascript seems to be the most suitable approach.

You can determine the necessary height (presumably of the current window) using JQuery, Prototype, or in pure Javascript: Retrieve the height of the current document and then

document.getElementById("text_area").style.height = calculated_height+"px";

The issue with left hand padding seems peculiar. Could you provide an example?

To tackle these types of issues, one must understand how browsers handle percentages. Contrary to popular belief, percentages do not actually exist in the browser; they are eventually converted to pixels. The process involves the browser rendering all tags, determining the size of outer and parent boxes in pixels based on percentage values, and setting the size of child boxes accordingly. A good starting point is to examine the size of the textarea's parent box, its parent box, and so forth. By inspecting the "Layout" information using tools like Firebug and IE Developer Toolbar, differences in measurements between browsers can be identified. Once these discrepancies are pinpointed, CSS adjustments can be made to accommodate them.

It is important to note that when using percentage sizing, the width and height of the parent box content, rather than padding, dictate the size of the child element. For example, if a parent box has a width of 500px and 100px of padding, a child element with a width set to 100% will also span 500px, with the padding surrounding it. As a result, both elements combined will occupy 700px of screen space.

Experiment with setting a min-height of 100% for the text area in your CSS. Make sure to add "position: relative" to the containing div that is set to absolute position.

Consider using transitional Doctypes instead of strict, and ensure all tags are properly closed. Striving for XHTML or HTML standard compliance can help avoid issues with cross-browser compatibility in the future.

To solve the height problem, consider including display:block and border:0 in your #text_area CSS styles. The first adjustment will address the height issue while the second one will prevent the width:100% from overflowing.
