I just need to style two-tone color background like this.

I tried and successfully did using linear gradient

background: linear-gradient(172deg, #ECB034 50%, #BE883C 50%);

But it has a problem when resizing web page. It just not well aligned to its corners. Showing weirdly. Like this

is there any way to did this?

.cta{
  padding: 60px 0;
  background: linear-gradient(172deg, #ECB034 50%, #BE883C 50%);
  text-align:center;
}

.cta h3{
  font-size: 58px;
  margin-bottom: 30px;
  font-weight: 700;
}

.cta a{
  padding: 16px 49px;
  border: 2px solid #000;
  color: inherit;
  font-size: 20px;
  text-transform: uppercase;
  display: inline-block;
  font-weight: 500;
}

This is a very simple fix with an SVG (as I mentioned in the comments) you simply need to add preserveAspectRatio="none" to the SVG tag and run it through a URL encoder. This one will even generate the CSS for you which is quite nice.

.cta{
  padding: 60px 0;
  background-image: url("data:image/svg xml,");
  text-align:center;
}

.cta h3{
  font-size: 58px;
  margin-bottom: 30px;
  font-weight: 700;
}

.cta a{
  padding: 16px 49px;
  border: 2px solid #000;
  color: inherit;
  font-size: 20px;
  text-transform: uppercase;
  display: inline-block;
  font-weight: 500;
}

You can use pseudo and clip-path combination.

.box{
  position:relative;
  background-color: #ecae20;
  text-align:center;
  margin: 30px;
  padding: 30px;
  z-index:1;
}

.box .content{
  position:relative;
  z-index:3;
}

.box:before {
  content: "";
  position:absolute;
  left:0;
  bottom:0;
  width: 100%;
  height: 100%;
  background-color: #BE883C;
  clip-path: polygon(0 99%, 100% 0, 100% 99%, 0 100%);
  opacity: 0.7;
  z-index:2;
}

    <button> GET STARTED > </button>    
  </div>
</div>

As the angle needed changes with the aspect ratio it is not possible to do this with linear-gradient without some recalculation on every resize.

However, it is possible to create a triangle with its hypoteneuse being a diagonal by using clip-path and a polygon.

There is no need to inline an SVG if you put the two colors as backgrounds to the before and after pseudo elements, the after also having a clip-path.

.cta {
  padding: 60px 0;
  text-align: center;
  position: relative;
}

.cta::before,
.cta::after {
  content: '';
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  z-index: -1;
}

.cta::before {
  background-color: #ECB034;
}

.cta::after {
  background-color: #BE883C;
  clip-path: polygon(0 100%, 100% 0, 100% 100%);
}

.cta h3 {
  font-size: 58px;
  margin-bottom: 30px;
  font-weight: 700;
}

.cta a {
  padding: 16px 49px;
  border: 2px solid #000;
  color: inherit;
  font-size: 20px;
  text-transform: uppercase;
  display: inline-block;
  font-weight: 500;
}

You don't need anything complex. Simply change the angle with to bottom right

.cta{
  padding: 60px 0;
  background: linear-gradient(to bottom right, #ECB034 50%, #BE883C 50%);
  text-align:center;
}

.cta h3{
  font-size: 58px;
  margin-bottom: 30px;
  font-weight: 700;
}

.cta a{
  padding: 16px 49px;
  border: 2px solid #000;
  color: inherit;
  font-size: 20px;
  text-transform: uppercase;
  display: inline-block;
  font-weight: 500;
}

You can use pseudo element for the same.

@import "https://cdn.jsdelivr.net/gh/KunalTanwar/normalize/css/normalize.inter.min.css";

body {
  height: 100%;
  display: grid;
  place-items: center;
}

.container {
  --container-width: 400px;
  --container-height: 200px;
  
  width: 100%;
  background-color: #ecb034;
  height: var(--container-height);
  max-width: var(--container-width);
}
.container::after {
  content: "";
  position: absolute;
  width: 0;
  height: 0;
  user-select: none;
  pointer-events: none;
  inset: auto 0 0 auto;
  border-bottom: var(--container-height) solid #be883c;
  border-left: var(--container-width) solid transparent;
}

<div ></div>

Make sure to keep border-left-width and width of the container same. And same for height.
