positioning checkboxes at the right side of the container and aligned vertically

I want the check boxes to be positioned like the image below:

enter image description here

Note that the checkboxes should be placed at the same vertical align.

Answer

Change .burmanRadio__label to have display inline-block instead of default inline, make it have an fixed width of 250px and set text-align to right adjust top, right, width and height properties accordingly to the layout and you’re done. Also remove height: 60% and use min-height: 60% instead, it will be better in most cases.

.feedback {
  background: rgb(242 237 241 / 90%);
  position: absolute;
  width: 90%;
  min-height: 60%;
  left: 5%;

Using flexbox and grid would be better.

Edit: If you need to align all the options to the right as on the image then you can just wrap then into a div and align it correctly.

.feedback {
  background: rgb(242 237 241 / 90%);
  position: absolute;
  width: 90%;
  min-height: 60%;
  left: 5%;
  top: 23%;
  display: flex;
  justify-content: center;
  align-items: stretch;
  box-shadow: 0px 2px 4px 4px #000000;
}

.feedback__form {
  padding: 20px;
  width: 100%;
  text-align: center;
}

.feedback__form h1 {
  font-weight: 700;
  margin-bottom: 15px;

button:active,

Make your own attempt before asking for code next time.
