洗掉特定螢屏尺寸的底部邊框

如您所見，在這種形式下，外邊框比內邊框輕

var x = window.matchMedia("(max-width: 992px)");
myFunction(x);
x.addListener(myFunction);

function myFunction(x) {
  if (x.matches) {
    document.getElementById("b-brdr").style.borderBottom = "none";
  }
}

@Md Mohtesham Azam 將此添加到您的 css 下面：

@media only screen and (max-width: 992px){
    #b-brdr { border-bottom:0 !important;}
}

這行得通嗎？

var x = window.matchMedia("(max-width: 992px)");
myFunction(x);
x.addListener(myFunction);

function myFunction(x) {
  if (x.matches) {
    var div_list = document.querySelectorAll('#b-brdr');
    var div_array = [...div_list]
    div_array.forEach(div => {
      div.style.cssText  = "border-bottom:none !important;";
    });
  }
  else{
    var div_list = document.querySelectorAll('#b-brdr');
    var div_array = [...div_list]
    div_array.forEach(div => {
      div.style.cssText  = "";
    });
  }
}
