What is the best way to adjust the height of a container to equal the viewport height minus a 300px height slider?

Question

What is the best way to adjust the height of a container to equal the viewport height minus a 300px height slider?

Forgive me for the rookie question, I know what I want to achieve should be simple but I seem to be having trouble articulating it in my search for solutions.

Essentially, I am trying to set a section in HTML to the height of the viewport minus the height of the navigation bar and a small slider at the bottom.

Do I need JavaScript to accomplish this? Any assistance would be greatly appreciated.

I've tried using the following CSS:

.container {
    height: 100%;
    margin-top: -300px;
    min-width: 100%;
}

.slider-wrapper {
    height: 300px;
    min-width: 100%;
}

However, this doesn't have the desired effect as it cuts off the top of the container. Is there some jQuery math that can be used to subtract the height of .slider from the height of .container?

As requested in the comments, here is additional markup, including only the container sections:

<section class="top-bar">
</section>

<section id="container">
</section>

<section class="slider-wrapper">
</section>

Those are the three containers that currently make up the layout of the screen. Here is the CSS for the #container:

#container {
    background: url(../img/cafe-background.jpg) no-repeat center center fixed;
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
    width: 100%;
    height: 100%;
    position: relative;
}

So, I just need to subtract the height of the .slider-wrapper from this container.

Answer №1

It appears that you are inquiring about utilizing calc() with viewport height units:

.container {
        height: calc(100vh - 300px);
}

Using jQuery:

You can see a live demonstration here

<head>
 <script src="https://code.jquery.com/jquery-2.1.0.min.js"></script>
 <script>
     $(document).ready(function () {
        var indexd = parseInt($(document).height()) - parseInt($('.slider-wrapper').css('height')) + 'px';
        $('#container').css('height', indexd);
     });
 </script>

Instead of relying on JavaScript, you can achieve the desired effects using the css3 calc function:

.container {
    height: calc(100% - 300px)
    min-width: 100%;
}

.slider-wrapper {
    height: 300px;
    min-width: 100%;
};

To automatically adjust the size of .slider-wrapper, consider nesting it within a section in your HTML markup like this:

<section id="container">
   <section class="slider-wrapper">
   </section>
</section>

If you are looking to achieve a layout similar to this example, here is how it can be done: The #top-bar and #slide-wrapper are fixed in position with preset heights. The #container fits between them by specifying top and bottom values, also with a fixed position.

However, a potential issue arises if the content within #container exceeds its height, resulting in a strange scrollbar behavior.

To address this problem, one solution is to change the position of #container to relative and add margin to the top and bottom accordingly.

It is worth noting that achieving this layout does not necessarily require CSS3 or JavaScript. Understanding the position property in CSS is key, and there are plenty of resources available online to help grasp its concept.

    width: 100%;
    background: blue;
    height: 100px;
    position: fixed;
    top: 0px;
}
#container{
    width: 100%;
    background: yellow;
    top: 105px;
    bottom: 105px;
    position: fixed;
}
#slider-wrapper{
    width: 100%;
    background: red;
    height: 100px;
    position: fixed;
    bottom: 0px;
}
