Manipulating elements with JavaScript to remove them, while ensuring that the empty space is automatically filled

Recently, I decided to enhance my understanding of JavaScript by experimenting with it on various websites.

My goal was to use JavaScript to remove the right bar from a webpage and have the remaining body text automatically fill in the space left behind.

While I successfully removed the right bar using JavaScript console, I encountered an issue where the rest of the content did not expand to cover the area. Is there a way to achieve this through JavaScript alone?

Check out the website where I am working on: https://docs.djangoproject.com/en/1.5/

Here is the JS code snippet I used:

child = document.getElementById("content-related");
child.parentNode.removeChild(child);

Answer №1

Take some time to familiarize yourself with the developer tools in your web browser. You can usually access them by pressing the F12 key. These tools will allow you to run commands in a console and inspect elements on the page.

When examining the hierarchy, you'll notice a div with the id of columnwrap which contains both content-main and content-related. While your command successfully removes an element, checking the styles of the content-main element reveals that it is set to a width of 70%, preventing it from reflowing and taking up remaining space.

To reset the width of the content-main element, you can simply adjust its width to either 100% or auto.

document.getElementById('content-main').style = 'width: 100%';
document.getElementById('content-main').style = 'width: auto';

Answer №2

The primary-content section occupies 70% of the entire width.

You can include one of these statements

document.getElementById('primary-content').setAttribute('width', '100%');

or use this alternative

document.getElementById('primary-content').style = 'width:auto';

Answer №3

Make sure to review the CSS file for any potential issues. Specifically, be aware that the width attribute of #content-main is currently set to 70%.

If you need the element to occupy the entire available space:

document.getElementById("content-main").style.width = '100%';
