How can I alter the curve of a radial gradient in CSS? - css

Question

I'm trying to achieve this gradient. What I don't understand is the curvature of it and I'm not sure on how to replicate it:
What I have so far:
and my code for the gradient:
radial-gradient(at top left,#629a92 36%,#02d2a0 67%, #fff 11%)
However I'm not sure how this gets stretched to the end of the screen. I haven't used radial-gradient much before so I feel like I'm missing something. Any help would be greatly appreciated. Thank you.

Answer 1

You need to also adjust background-size of the gradient:
body {
height:100vh;
margin:0;
background-image:radial-gradient(at top left,#629a92 36%,#02d2a0 67%, transparent 67.5%);
background-size:120% 100%;
background-repeat:no-repeat;
}
Or adjust the radius:
body {
height:100vh;
margin:0;
background-image:radial-gradient(120% 100% at top left,#629a92 61%,#02d2a0 92%, transparent 92.5%);
background-repeat:no-repeat;
}
UPDATE
If it's a linear-gradient inside a curved shape you can try to use multiple background. The idea is to create the linear-gradient and above it you add the a radial-gradient with transparent color to be able to see the first gradient.
body {
height:100vh;
margin:0;
background-image:
radial-gradient(120% 100% at top left,transparent 92%, #fff 92.5%),
linear-gradient(135deg, #51a595 0%, #3fcfa2 100%);
}

Answer 2

If you look carefully it is not a radial gradient. It is a linear gradient inside a radial shape. If I were you, I would do a SVG shape—mine is just for using as example—and apply it to the gradient.
Like this:
body {
margin: 0;
}
svg {
width: 0;
height: 0;
display: block;
}
.main {
width: 100%;
height: 100vh;
position: relative;
}
.main:before {
content: '';
position: absolute;
overflow: hidden;
width: 100%;
height: 100%;
background: #51a595;
background: linear-gradient(135deg, #51a595 0%, #3fcfa2 100%);
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#51a595', endColorstr='#54bb9b',GradientType=1 );
-webkit-clip-path: url("#mask");
clip-path: url("#mask");
}
<svg>
<defs>
<clipPath id="mask">
<ellipse cx="0" cy="-1400" rx="2200" ry="1500"></ellipse>
</clipPath>
</defs>
</svg>
<div class="main"></div>

Looking at radial-gradient on mdn, it can take 2 percentages before the at top left for its size. We can make the first larger than 100% so it will extend beyond the screen on the x axis and put the second percent to 100% so it ends at the bottom.
radial-gradient(
200% 100% at top left,
#629a92 36%,
#02d2a0 67%,
#fff 11%
);
This should result in what you are looking for
.head {
width: 100%;
height: 200px;
background: radial-gradient(
200% 100% at top left,
#629a92 36%,
#02d2a0 67%,
#fff 11%
)
}
.body {
height: 200px;
width: 100%;
}
<div class="head"></div>
<div class="body"></div>
