Question

Tips for preserving CSS layout when incorporating new content in an ASP.NET project

Presented below is a page in ASP.NET.

To view the JSFIDDLE code, click on the link provided: http://jsfiddle.net/nyrUp/

HTML

    <div class="mainContainer">
        <div>
            <div class="topLeft">
                <% =DateTime.Now.Ticks.ToString()%>
            </div>
            <div class="topRight">
                foo
            </div>
        </div>
        <div>
            <div class="bottomLeft">
                foo
            </div>
            <div class="bottomRight">
                foo
            </div>
        </div>

        <div class="underneath">
            foo
        </div>
    </div>

CSS

.mainContainer {
}
.topLeft {
    width: 50%;
    float: left;
    background-color: red;    
}

.topRight {
    width: 50%;
    float: left;
    background-color: orange;
}

.bottomLeft {
    width: 50%;
    float: left;
    background-color: yellow;
}

.bottomRight {
    width: 50%;
    float: left;
    background-color: green;
}

.underneath {
    width: 100%;
    background-color: blue;
}

The layout functions properly initially, but inserting content into any div disrupts it.

To see the layout break in the JSFIDDLE simulation, click here: http://jsfiddle.net/4gbP8/

Could you please advise on how to sustain this layout when content is introduced?

Thank you!

Answer 1

Answer №1

By placing a container on the blank top div, I was able to contain them. It seems like you want each box to fill the page.

http://jsfiddle.net/4gbP8/2/ CSS ADD

.top {
   display: inline-block;
   width: 100%;
   height: 100%;

 }

HTML

       <div class="top">
            <div class="topLeft">
                <p>123</p>
                <p>123</p>
                <p>123</p>
                <p>123</p>
            </div>
            <div class="topRight">
                foo
            </div>

If you have the ability to modify the HTML, I have a solution that involves adding a new class.

I have included a class called clear to help organize the different levels and give them more structure.

JSFIDDLE

CSS

.clear{clear:both;}

HTML

 <div class="mainContainer">
            <div class="clear">
                <div class="topLeft">
                    <p>123</p>
                    <p>123</p>
                    <p>123</p>
                    <p>123</p>
                </div>
                <div class="topRight">
                    foo
                </div>
            </div>
            <div class="clear">
                <div class="bottomLeft">
                    foo
                </div>
                <div class="bottomRight">
                    foo
                </div>
            </div>

            <div class="underneath clear">
                foo
            </div>
        </div>

Feel free to let me know if this solution works for you, or if there are any adjustments I can make to improve it further.

Answer №3

You have 2 challenges

If you want to maintain the column distribution, you need to clear the floats

To preserve the backgrounds, you should utilize negative margins and exaggerated paddings

You will achieve this effect

( Check out this demo on Fiddle for a complete example)

Make sure to create wrappers for each set of floating elements and apply some CSS for the negative margin technique. The markup should look like this:

<div class="mainContainer">
            <div class="wrapper">
                <div class="topLeft">
                    <p>123</p>
                    <p>123</p>
                    <p>123</p>
                    <p>123</p>
                </div>
                <div class="topRight">
                    foo
                </div>
            </div>
            <div class="wrapper">
                <div class="bottomLeft">
                    foo
                </div>
                <div class="bottomRight">
                    <p>123</p>
                    <p>123</p>
                    <p>123</p>
                    <p>123</p>

                </div>
            </div>

            <div class="underneath clear">
                foo
            </div>
        </div>

Each floating div should have the following styles applied:

{
   ...
    padding-bottom:2000px;
    margin-bottom:-2000px;
...
}

The ....left divs should have the following style:

{
  ...
  clear:left;
...
}

Also, remember to include the following wrapper style for each pair of floating divs:

.wrapper {
    overflow:hidden;
}

                    <p>123</p>
                    <p>123</p>

                </div>
            </div>

            <div class="underneath clear">
                foo
            </div>
        </div>

Utilizing the table and table-cell display properties can achieve the desired outcome:

http://jsfiddle.net/4gbP8/3/

.mainContainer {
}

.mainContainer > div {
    display: table;
    width: 100%;
}
.topLeft {
    width: 50%;
    display: table-cell;
    background-color: red;    
}

.topRight {
    width: 50%;
    display: table-cell;
    background-color: orange;
}

.bottomLeft {
    width: 50%;
    display: table-cell;
    background-color: yellow;
}

.bottomRight {
    width: 50%;
    display: table-cell;
    background-color: green;
}

.underneath {
    width: 100%;
    background-color: blue;
}

To ensure responsive design for smaller devices, use media queries to adjust the display properties for wider screens.
