how do i hide an image only on mobile devices using bootstrap
You can hide an image on mobile devices using Bootstrap's built-in d-none d-md-block classes. To hide an image on small screens, use d-none d-sm-block instead. Here's an example:
html Copy code
<img src="myimage.jpg" class="d-none d-sm-block">
This code will cause the image to be hidden on devices with a max-width of 576px. To learn more about the responsive utilities in Bootstrap, check out the official documentation here:
https://getbootstrap.com/docs/4.5/utilities/display/#responsive-display
@media for bootstrap 5
In Bootstrap 5, the use of @media has been simplified. It still supports the same media queries syntax as previous versions, but now @media will apply the same breakpoint values to all of the display options. For example, @media (max-width: 576px) {} will now apply to any display option such as xs, sm, md, lg, xl and xxl. Here's an example from the Bootstrap docs:
css Copy code
/* Extra small devices (portrait phones, less than 576px) */
@media (max-width: 575px) { ... }
/* Small devices (landscape phones, 576px and up) */
@media (min-width: 576px) and (max-width: 767px) { ... }
/* Medium devices (tablets, 768px and up) */
@media (min-width: 768px) and (max-width: 991px) { ... }
/* Large devices (desktops, 992px and up) */
@media (min-width: 992px) and (max-width: 1199px) { ... }
/* Extra large devices (large desktops, 1200px and up) */
@media (min-width: 1200px) { ... }
You can find more information in the Bootstrap 5 documentation.
Bootstrap how to make col item not take space when it's display none
Using Bootstrap, you can make an individual columns not take up any space when the display:none CSS property is set by using the order-* and d-* classes. For example:
html Copy code
<div class="row">
<div class="col-6 order-1 order-md-2 d-none d-md-block">Item 1</div>
<div class="col-6 order-2 order-md-1">Item 2</div>
</div>
By setting the order-1 and d-none classes on the Item 1 column, it will not take up the space on mobile devices and tablets, but will on larger displays. On larger displays, it will appear in between Item 1 and Item 2 (via order-md-2). For more information, please see Bootstrap's documentation on responsive ordering.
how to add a border with bootstrap?
We can use Bootstrap's built-in border classes to create various border styles.
To add a border to any element, add the class .border to the element.
If you'd like to add a specific border style, such as a dashed border, you can use the .border-* classes.
For example, you can use the .border-dashed class to create a dashed border like this:
html Copy code
<div class="border border-dashed">
Example border
</div>
If you inspect the element, you will see something like this:
css Copy code
.border-dashed {
border-style: dashed;
}
For more information on border classes, see the Bootstrap documentation.

Not likely. AI can automate tasks and make developers' jobs more efficient but it can't fully replace the human ability to deal with complex software. And AI will still require human developers to supervise and improve it further.
So developers may see their tasks change but they won't be replaced by AI. ๐ฉโ๐ป๐ค๐ป
