proper method for concealing HTML content

Currently, I am developing a simple HTML+JavaScript application where the user must choose between two options using radio buttons. Once a choice is made, either content "A" or content "B" should be displayed beneath the radio buttons.

I am considering the best approach to handle this content. Should I create 2 DIVs, with only one visible depending on the option chosen, or should I use JavaScript to dynamically change the InnerHTML of a single div based on the state of the radio buttons? This application does not involve submitting form data as it's more of a calculation tool.

Thank you for your input! J

Answer №1

If you want to hide an element, you have a few options:

.myElementHidden
{
   display: none;
}

.myElementVisible
{
   display: block;
}

<div id="myElement">
   Content
</div>

or 

.myElementInvisible
{
   visibility: hidden;
}
.myElementVisible
{
   visibility: visible;
}

<div id="myElement">
   Content
</div>

The main difference is that display: none; will completely remove the element from view, while visibility: hidden; will hide it but still reserve the space it occupies.

You can switch between these styles using JavaScript:

if (condition goes here)
{
   document.getElementById('myElement').className = className; // display or visibility
}
else
{
   document.getElementById('myElement').className = className; // display or visibility
}

Simply toggle between the visibility classes based on your preference.

Answer №2

To achieve a hidden display effect, utilize two divs with a CSS class containing the rule display: none. Once a user makes a selection, modify the CSS to show the desired div and hide the other one. For instance, if choice 1 is selected:

div1.style.display = 'block';
div2.style.display = '';

Answer №3

Splitting content into multiple divs and showing only the necessary one is more efficient. Trying to dynamically generate content can complicate the design process without adding any significant benefit.

Answer №4

Utilize the power of 2 separate divs for cleaner code organization. Avoid embedding HTML directly into Javascript as it can be unattractive and complicate page layout.

Answer №5

To hide the div, utilize both divs and apply the style display: none;.
