Links in footer wont display inline

I'm trying to put some links in a footer next to each other, separated by the character "|". But I have a navbar whose styles interferes with the footer's links.
I need something like this :
This is my code (it doesn't display perfectly, but you get the gist):
#import url('https://fonts.googleapis.com/css2?family=Poppins:wght#200;300;400;500&display=swap');

As you can see the links aren't displaying inline. How can I fix this?

Wrap the links in a div with a class (I gave it footer-links) and give it the following styles:
.footer-links {
display: flex;
justify-content: center;
align-items: center;
}
#import url('https://fonts.googleapis.com/css2?family=Poppins:wght#200;300;400;500&display=swap');

}
.collapsible {
width: 100%;
border: 0px;

}
This is my JS:
var coll = document.getElementsByClassName('collapsible')
for (let i = 0; i < coll.length; i++) {
coll[i].addEventListener('click', function() {
this.classList.toggle('active')
var content = this.nextElementSibling
if (content.style.maxHeight) {
content.style.maxHeight = null
} else {
content.style.maxHeight = content.scrollHeight + "px"
}
})
}

Using .nextSibling will look directly for the next child element under your parent div. Since this refers to your button inside of chat-bar-collapsible there are no more child elements that are adjacent to your button element under the char-bar-collapsible div. You need to walk up to the parent element using .parentNode, and then access the adjacent content div from that using .nextElementSibling:
var content = this.parentNode.nextElementSibling;
var coll = document.getElementsByClassName('collapsible');
for (let i = 0; i < coll.length; i++) {
coll[i].addEventListener('click', function() {
this.classList.toggle('active');
var content = this.parentNode.nextElementSibling;
if (content.style.maxHeight) {
content.style.maxHeight = null
} else {
content.style.maxHeight = content.scrollHeight + "px"
}
})
}

I want the corner of the blog card to be perfectly aligned under the corner of the iFrame. The first corner of the blog card should be right under the first corner of the iFrame.
Expected Output
Expected Output
How would I modify the CSS to have it output as the above picture? Adding margin-left: auto on square does not work. Any suggestions would greatly help! Thanks a lot!

My suggestion is to remove the grid and padding from .container1, align the iframe left, and set both left margins to 10%.
Since the iframe is width:80%, 10% on each side will center it. And the matching margin on the top element will align the left edges of the two elements.

I have this piece of code that has the profile card in the middle of screen regardless what the screen size is. It often appears too small for any type of screen. How can I position the profile card to almost fill the screen?
Basically what should I do to adjust it from (too small)to this (ideal)

Just change it:
.shots .shot {
overflow: hidden;
position: relative;
width: 33%; // <-- change it
height: 100px;
flex-grow: 1; // <-- add
}

I would use media queries and target the classes you want to amend on the different screen sizes to make it fit as you need. Some useful links:
https://css-tricks.com/snippets/css/media-queries-for-standard-devices/
https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries
In your case, you would need to amend the width of the card to 100% on mobile to achieve the design on your screenshot. Hope that makes sense! :)

Text getting misaligned on hover

I'm building an image component with caption.
When the user mouse hover on the text on hover of the div element, it is changing the position of the text:
JSFiddle URL: https://jsfiddle.net/9jkze0o4/
CSS:
.inner-div {
position: relative;
display: inline-block;
box-shadow: 0 0px 15px 0px #d5d5d5;
padding: 0px;
margin: 0px;
position: relative;
display: inline-block;
border-style: solid;
border-width: 2px;
border-color: rgb(67, 67, 67);
background-color: rgb(204, 204, 204);
width: 150px;
height: 150px;
}
.inner-div:hover {
box-shadow: 0 0px 15px 0px #d5d5d5;
border-style: solid;
border-width: 28px;
border-color: rgb(67, 67, 67);
background-color: rgb(204, 204, 204);
}
.inner-div:hover .overlay {
display: block;
opacity: 1;
background: rgba(52,152,219,0.49);
border-radius: 13px;
text-align: center;
}
.inner-div .overlay:hover .overlay-icon i {
display: block;
position: absolute;
top: 40%;
-webkit-transform: translateX(-50%) translateY(-4%);
-ms-transform: translateX(-50%) translateY(-4%);
transform: translateX(-50%) translateY(-4%);
opacity: 1;
left: 50%;
}
On hover of the image, how to keep the text position as is?

Looks like your selector is not right when hovering. When hovering the inner-div all the styles applies to everything inside that block including the caption. To overcome this problem you will need to give the :hover to the box.
You can change this,
innder-div:hover
to be this,
box:hover
in your styles.
See the fiddle - https://jsfiddle.net/anjanasilva/jkwL3n0g/
Hope this helps.
Cheers.

You have to change inner-div:hover to box:hover
Here's a working Fiddle: https://jsfiddle.net/9jkze0o4/3/

This issue is because of the border-width:28px to class .inner-div:hover remove .inner-div:hover and give border to class .inner-div:hover .box as shown below:
.inner-div:hover .box {
border: 28px solid rgb(67, 67, 67);
}
