Hi
I am trying to create a column that will always have remaining width. However I want it consist of 3 divs as the middle div will always fill the width available where as the left and right divs will be a fixed width. The problem I have is that the middle div which has remaining width knocks the other divs onto a new line. How can I prevent this?

Appear on Left, this would be fixed width

Always be remainging width

Appear Right, this would be fixed width

note :
something the left div will have no controls in it.
many thanks in adavance

I'm working on my mobile, so apologies in advance for the lack of formatting / example code.
In principle it's pretty simple, once you know how:
1. Create a div as a container.
2. Into the above place three divs left,right and middle in that order
3. Using CSS float the left div left and the right div. ALSO set the widths
4. Using CSS set the left margin and right margin of the middle div so
it doesn't run round the divs on the edge.

You might also need to Google cleafix if you want to support other browsers.

A round up of the above can be seen here:

CSS sibling selectors will help. You might even be able to use the general sibling combinator[^]:

HTML

<div class="wrapper">
   <div class="left-column">
      Left column content.
   </div>
   <div class="right-column">
      Right column content.
   </div>
   <div class="main-column">
      Main column content.
   </div>
</div>

CSS

.left-column
{
   float: left;
   width: 120px;
}
/* If the main column is preceded by a left column, add a left margin: */
.left-column ~ .main-column
{
   margin-left: 120px;
}

.right-column
{
   float: right;
   width: 120px;
}
/* If the main column is preceded by a right column, add a right margin: */
.right-column ~ .main-column
{
   margin-right: 120px;
}

/* Clear the column floats: */
.wrapper:after
{
   content: "";
   display: table;
   clear: both;
}

Thanks All!

But i wanna somthing like this :

ASP.NET

<div style="width: 100%;">
     <div style="width:15%;float:right"><asp:TextBox runat="server" Width="120px"></asp:TextBox></div>
    <div style="float:right;width:100%"><asp:TextBox ID="TextBox2" runat="server" Width="100%"></asp:TextBox></div>
    <div style="width:15%;float:left"><asp:TextBox ID="TextBox1" runat="server" Width="117px"></asp:TextBox></div>
</div>

and user can remove center texbox in settings and it will be like this :

ASP.NET

<div style="width: 100%;">
     <div style="width:15%;float:left"><asp:TextBox runat="server" Width="120px"></asp:TextBox></div>
    <div style="float:left;"><asp:TextBox ID="TextBox2" runat="server" Width="100%"></asp:TextBox></div>
    <div style="width:15%;float:left"></div>
</div>

Now Center div should take the left div width too.

Example 2 :

first i have :

ASP.NET

<div class="wrapper">
        <div class="left-column">
             <asp:TextBox ID="TextBox1" runat="server" Width="100%">Left</asp:TextBox>
        </div>
        <div class="right-column">
            <asp:TextBox ID="TextBox2" runat="server" Width="100%">Rigth</asp:TextBox>
        </div>
        <div class="main-column">
           <asp:TextBox ID="TextBox3" runat="server"  >content</asp:TextBox>
        </div>
    </div>

and the user can change remove the left textbox in left div :

ASP.NET

<div class="wrapper">
        <div class="left-column">
             
        </div>
        <div class="right-column">
            <asp:TextBox ID="TextBox2" runat="server" Width="100%">Rigth</asp:TextBox>
        </div>
        <div class="main-column">
           <asp:TextBox ID="TextBox3" runat="server"  >content</asp:TextBox>
        </div>
    </div>

Now the center div should "Stretch".

You are correct the style sheets for element id seems to not work. This is because asp controls are by default renderend with name and id attributes set to unique values.
As a result you don't have to worry about having <asp:button id="Button"> on master page, content page and 3 copies of the same user control - they all will get different id, avoiding problems with html validation and event handling.

If you absolutely have to use css with id and you know 100% there will be no other control with the same ID, you can set ClientIDMode="static", however I would encourage using css class instead (set with "CssClass" attribute for asp controls, not "class" as in your example".

On final note, you can check exact id and other properties of rendered page using F12 tool in most browsers.

You have to consider the screen space availability of mobile and design accordingly. Following W3C standards, you can develop UI that will be compatible across browsers.

If you have some fixed width as per pc browser, it will have an affect on mobile.

You should give a try to bootstrap as your css. It provides Cross platform support, which eliminates major layout inconsistencies. Some of the benefits it provide are:

-12-Column Grid, fixed layout, fluid or responsive layout.
-Base CSS for Typography, code (syntax highlighting with Google prettify), Tables, Forms, Buttons and uses Icons by Glpyhicons .
-Web UI Components like Buttons, Navigation menu, Labels, Thumbnails, Alerts, Progress bars and misc.
-Javascript plugins for Modal, Dropdown, Scrollspy, Tab, Tooltip, Popover, Alert, Button, Collapse, Carousel and Typehead.
