Avoid an element to be split into two columns while using column-count

问题

I am trying to make a group of <a> using multiple columns. But it splits one <a> (Link4) into two columns. :( Just hover on Link4. Some of its part is split to second column. :( Is there any possible way to avoid this.

div.Nav {
  height: 100% !important;
}

div.Nav a.icon {
  position: absolute;
  right: 0;
  top: 0;
}

div.Nav a {
  transition: 0.5s;
  line-height: 25px;
  text-align: center;
  font-weight: lighter;
  color: black;
  padding: 8px 16px;
  text-decoration: none;
  font-size: 20px;
  float: none !important;
  display: block;
  text-align: left;
}

div.Nav a.active {
  background-color: #4CAF50;
  color: white;
  cursor: default;
}

div.Nav a:hover:not(.active) {
  background-color: rgb(56, 62, 50);
  color: #fffd78;
  transition: 0.5s;
}

div.Nav div.newspaper {
  -webkit-column-count: 3;
  -moz-column-count: 3;
  column-count: 3;
  -webkit-column-rule: 2px grey solid;
  -moz-column-rule: 2px grey solid;
  column-rule: 2px grey solid;
  -webkit-column-gap: 0;
  -moz-column-gap: 0;
  column-gap: 0;
}

回答1:

Use break-inside: avoid; (or the propriety equivalents) to prevent the tags from flowing into the next column:

div.Nav {
  height: 100% !important;
}

div.Nav a.icon {
  position: absolute;
  right: 0;
  top: 0;
}

div.Nav a {
  transition: 0.5s;
  line-height: 25px;
  text-align: center;
  font-weight: lighter;
  color: black;
  padding: 8px 16px;
  text-decoration: none;
  font-size: 20px;
  float: none !important;
  display: block;
  text-align: left;
  
  -webkit-column-break-inside: avoid; /* Chrome, Safari, Opera */
  page-break-inside: avoid; /* Firefox */
  break-inside: avoid; /* IE 10+ */
}

div.Nav a.active {
  background-color: #4CAF50;
  color: white;
  cursor: default;
}

div.Nav a:hover:not(.active) {
  background-color: rgb(56, 62, 50);
  color: #fffd78;
  transition: 0.5s;
}

div.Nav div.newspaper {
  -webkit-column-count: 3;
  -moz-column-count: 3;
  column-count: 3;
  -webkit-column-rule: 2px grey solid;
  -moz-column-rule: 2px grey solid;
  column-rule: 2px grey solid;
  -webkit-column-gap: 0;
  -moz-column-gap: 0;
  column-gap: 0;
}
