I'm a beginner and very confused, as a div tag when I give the same width and height with border-radius: 50% it always becomes circle. but with the tag a in case I want to make a circle button, It doesnt work that way. This is when I try to make a circle border button clickable.
.btn {
height: 300px;
width: 300px;
border-radius: 50%;
border: 1px solid red;
}<a class="btn" href="#"><i class="ion-ios-arrow-down"></i></a>

For div tag there is already default property display:block given by browser. For anchor tag there is not display property given by browser. You need to add display property to it. That's why use display:block or display:inline-block. It will work.
.btn {
display:block;
height: 300px;
width: 300px;
border-radius: 50%;
border: 1px solid red;
}<a class="btn" href="#"><i class="ion-ios-arrow-down"></i></a>.round-button {
width:25%;
}
.round-button-circle {
width: 100%;
height:0;
padding-bottom: 100%;
border-radius: 50%;
border:10px solid #cfdcec;
overflow:hidden;
background: #4679BD;
box-shadow: 0 0 3px gray;
}
.round-button-circle:hover {
background:#30588e;
}
.round-button a {
display:block;
float:left;
width:100%;
padding-top:50%;
padding-bottom:50%;
line-height:1em;
margin-top:-0.5em;
text-align:center;
color:#e2eaf3;
font-family:Verdana;
font-size:1.2em;
font-weight:bold;
text-decoration:none;
}<div class="round-button"><div class="round-button-circle"><a href="" class="round-button">Button!!</a></div></div>or very simple for <a/>
.round-button {
display:block;
width:80px;
height:80px;
line-height:80px;
border: 2px solid #f5f5f5;
border-radius: 50%;
color:#f5f5f5;
text-align:center;
text-decoration:none;
background: #555777;
box-shadow: 0 0 3px gray;
font-size:20px;
font-weight:bold;
}
.round-button:hover {
background: #777555;
}<a href="" class="round-button">Button</a>for jsfiddle reference click here
Here is a flat design circle button:
.btn {
height: 80px;
line-height: 80px;
width: 80px;
font-size: 2em;
font-weight: bold;
border-radius: 50%;
background-color: #4CAF50;
color: white;
text-align: center;
cursor: pointer;
}<div class="btn">+</div>but the problem is that the + might not be perfectly centered vertically in all browsers / platforms, because of font differences... see also this question (and its answer): Vertical alignement of span inside a div when the font-size is big
Add display: block;. That's the difference between a <div> tag and an <a> tag
.btn {
display: block;
height: 300px;
width: 300px;
border-radius: 50%;
border: 1px solid red;
}
use this css.
.roundbutton{
display:block;
height: 300px;
width: 300px;
border-radius: 50%;
border: 1px solid red;
}<a class="roundbutton" href="#"><i class="ion-ios-arrow-down"></i></a>For a modern CSS approach, we now have a few tools like aspect-ratio and grid to create perfect circle buttons like so:
aspect-ratio: 1;
border-radius: 50%;
display: grid;
place-items: center;
Setting fixed height and width on an inline element (i.e an a tag) has no effect. Like mentioned by the others, we need to set the display property to a block element. Using grid allows easy centering and generally more control of the content inside the button.
All together with some optional padding and centering:
(Leaving the red border because OP had it on there)
.btn {
aspect-ratio: 1;
border-radius: 50%;
display: grid;
place-items: center;
padding: 0 2em;
border: 1px solid red;
}
This is now compatible with all modern browsers. Of course your project may not allow such modernity but it is nice to start using this stuff when we can.
Though I can see an accepted answer and other great answers too but thought of sharing what I did to solve this issue (in just one line).
CSS ( Created a Class ) :
.circle {
border-radius: 50%;
}
HTML (Added that css class to my button) :
<a class="button circle button-energized ion-paper-airplane"></a>
So Easy Right ?
Note : What I actually did was proper use of ionic classes with just one line of css.
See Result your self on this JSFiddle :
HTML:
<div class="bool-answer">
<div class="answer">Nej</div>
</div>
CSS:
.bool-answer {
border-radius: 50%;
width: 100px;
height: 100px;
display: flex;
justify-content: center;
align-items: center;
}
For create circle button you are this codes:
.circle-right-btn {
display: block;
height: 50px;
width: 50px;
border-radius: 50%;
border: 1px solid #fefefe;
margin-top: 24px;
font-size:22px;
}<input class="circle-right-btn" type="submit" value="<">An round button with box-shadow
.btn {
height: 50px;
width: 50px;
line-height: 50px;
font-size: 2em;
border-radius: 50%;
background-color: red;
color: white;
text-align: center;
border: none;
cursor: pointer;
position: fixed;
z-index: 1;
bottom: 10%;
right: 4%;
box-shadow: 0 3px 5px -1px rgba(0, 0, 0, 0.2), 0 6px 10px 0 rgba(0, 0, 0, 0.14), 0 1px 18px 0 rgba(0, 0, 0, 0.12);
}<div class="btn">+</div>The problem is that the actual width of an a tag depends on its contents. Your code has no text in the a tag, so it appears like a hunger-sunken circle. If you use the div tag along the a, you get the desired results.
Check this code out:
.btn {
background-color: green;
border-radius: 50%;
/*this will rounden-up the button*/
width: 80px;
height: 80px;
/*keep the height and width equal*/
}<a href="#">
<!--use the URL you want to use-->
<button class="btn">press me</button>
</a>you could always do
html: <div class = "btn"> <a> <button> idk whatever you want to put in the button </button> </a> </div>
and then do
css:
.btn a button { border-radius: 50% }
works perfect in my opinion
if you want a more generic solution that will resize with the size of the screen you can use this example.
.btnCircle {
border-radius: 50% ;
padding: 3vw;
display: flex;
justify-content: center;
align-items: center;
width:3vw;
height:3vw;
font-size: 2vw;
outline:none;
border: none;
}
.btnBackgroundColor{
background: green;
}
.btnColor{
color: white;
}
<button class="btnCircle btnBackgroundColor btnColor">Yes</button>
