Angular Primeng carousel - 自定义 Prev 和 Next 按钮

Question

I have explained everything in the attached image. and all CSS code are in the stackblitz.

Basically I want a customized Next and Prev button. I want the border of the Next and Prev button to be same as the inside boxes. and with rounded corner. (that means to show that there is a Prev or Next box still available so use can click on Next/Prev

The problem I am getting now is when I click on the Next/Prev, the border is getting bold and blue. I believe it is coming from the default browser(not sure though)

Answer 1

There's a box-shadow that is added when the button is focused.

You can remove it with this style:

::ng-deep .p-carousel .p-carousel-content .p-carousel-prev:focus {
  box-shadow: none;
}

Also, I think this is what you mentioned in the image, but the previous button have border width set to thick, it should be changed to thin to match the next button:

::ng-deep .p-carousel .p-carousel-content .p-carousel-prev {
  width: 2.513rem;
  height: 5.68rem;
  border-radius: 25%;
  border-right-color: #99bbff;
  border-right-style: solid;
  border-right-width: thin;
  border-top-color: #99bbff;
  border-top-style: solid;
  border-top-width: thin;
  border-bottom-color: #99bbff;
  border-bottom-style: solid;
  border-bottom-width: thin;
  margin: 0 0 0 -5px;
}

Answer 2

do you want to keep the blue border? because this is enough to edit your buttons:

.p-carousel-next, .p-carousel-prev {
  box-shadow: none !important;
  border-width: 1px !important;

  /* if you wish to remove the border or change its color */
  /* border: transparent !important; */
}
