margin-top is not working - html

Question

I'm trying to implement a popup at the bottom right corner of my web in WordPress.
The popup is working properly, but I have 2 lines of text, a message and a button. Everything was okay since I wanted to put a margin-top in the button because the button was covering the text.
Here you can see the HTML code and the CSS.
#corner-slider {
position: fixed;
z-index: 10000;
overflow: hidden;
border-radius: 15px;
color: white;
padding: 10px;
margin-bottom: 60px;
height: 120px;
width: 369px;
border: 1px solid #2d93f1;
background: #2d93f1;
}
#corner-slider.hidden {
display: none;
}
#corner-slider .close {
position: absolute;
cursor: pointer;
font-size: 16px;
display: inline-block;
z-index: 1002;
right: 24px;
top: 10px;
}
.popup-button {
padding: 8px 30px;
background-color: #ffffff;
border-color: #ffffff;
border-radius: 45px;
margin-top: 240px;
}
<div id="corner-slider">
Do you want to stay here?
<br />
<a target="_blank" href="#" class="popup-button">Click me!</a>
</div>
So, why is margin-top not working? What can I do?
Thanks.

Answer 1

The anchor element <a> is an inline element. Change its display type to inline-block or block:
#corner-slider {
position: fixed;
z-index: 10000;
overflow: hidden;
border-radius: 15px;
color: white;
padding: 10px;
margin-bottom: 60px;
height: 120px;
width: 369px;
border: 1px solid #2d93f1;
background: #2d93f1;
}
#corner-slider.hidden {
display: none;
}
#corner-slider .close {
position: absolute;
cursor: pointer;
font-size: 16px;
display: inline-block;
z-index: 1002;
right: 24px;
top: 10px;
}
.popup-button {
padding: 8px 30px;
background-color: #ffffff;
border-color: #ffffff;
border-radius: 45px;
display: inline-block;
margin-top: 1em;
}
<div id="corner-slider">
Do you want to stay here?
<br />
<a target="_blank" href="#" class="popup-button">Click me!</a>
</div>

button is not stable, just add disply:inline-block or float:left
#corner-slider {
position: fixed;
z-index: 10000;
overflow: hidden;
border-radius: 15px;
color: white;
padding: 10px;
margin-bottom: 60px;
height: 120px;
width: 369px;
border: 1px solid #2d93f1;
background: #2d93f1;
}
#corner-slider.hidden {
display: none;
}
#corner-slider .close {
position: absolute;
cursor: pointer;
font-size: 16px;
display: inline-block;
z-index: 1002;
right: 24px;
top: 10px;
}
.popup-button {
padding: 8px 30px;
background-color: #ffffff;
border-color: #ffffff;
border-radius: 45px;
margin-top: 10px;
display: inline-block; /* newly added */
}
<div id="corner-slider">
Do you want to stay here?
<br />
<a target="_blank" href="#" class="popup-button">Click me!</a>
</div>

<style>
#corner-slider {
