如何为两列添加单一渐变颜色？

标签： javascript css twitter-bootstrap multiple-columns linear-gradients

我有两个表列数据<td>，一个是日期，另一个是时间。现在，我想添加一个渐变颜色，它从日期开始，以时间结束，如下图所示。我正在使用Bootstrap 3.3.5，Javascript，Jquery。

是否可以添加渐变颜色或需要使用“数据和时间”创建单个列？

有什么建议吗？？

您可以局部应用渐变

.a {
  background-image: linear-gradient( to right, red 80%, white);
  border-right: 1px solid green;
  color: yellow;
}

.b {
  background-image: linear-gradient( to right, red 80%, white);
  border-left: 1px solid red;
  color: yellow;
}
<table>
  <tr>
    <td class="a">Date</td>
    <td class="b">Time</td>
  </tr>
</table>

table, th, td {
  border: 1px solid black;
  color:red
}
.date {
  -webkit-column-width: 100px; /* Chrome, Safari, Opera */
  -moz-column-width: 100px; /* Firefox */
  column-width: 100px;
  background-image: linear-gradient(90deg, black, gray);
}
.time {
  -webkit-column-width: 100px; /* Chrome, Safari, Opera */
  -moz-column-width: 100px; /* Firefox */
  column-width: 100px;
  background-image: linear-gradient(90deg, gray, white);
}

由于您要为列设置一个固定的，因此您可以简单地调整background-size使其具有两列的大小并调整background-position。为了更准确，您还需要考虑border-spacing和边框（在您的情况下，边框的间距为2px，边框的总数为4px）

table, th, td {
  border: 1px solid black;
}
.date {
  -webkit-column-width: 100px; /* Chrome, Safari, Opera */
  -moz-column-width: 100px; /* Firefox */
  column-width: 100px;
  background: linear-gradient(90deg, red, yellow) left/206px 100%;
}
.time {
  -webkit-column-width: 100px; /* Chrome, Safari, Opera */
  -moz-column-width: 100px; /* Firefox */
  column-width: 100px;
  background: linear-gradient(90deg, red, yellow) right/206px 100%;
}
<table>
    <tr>
    <th>Monthly Savings</th>
    <th>Date</th>
    <th>Time</th>
    <th>Paper</th>
    <th>Pen</th>
  </tr>
  <tr>
    <td>January</td>
    <td class="date">21/1/2019</td>
    <td class="time">10:13</td>
    <td>white</td>
    <td>Black</td>
  </tr>
  <tr>
    <td>February</td>
    <td class="date">22/2/2019</td>
    <td class="time">10:23</td>
    <td>Black</td>
    <td>white</td>
  </tr>
  <tr>
    <td>March</td>
    <td class="date">3/3/2019</td>
    <td class="time">3:23</td>
    <td>blue</td>
    <td>red</td>
  </tr>
</table>

如果您更改列的宽度，也可以使用，只需确保总和得到遵守即可：

table, th, td {
  border: 1px solid black;
}
.date {
  -webkit-column-width: 50px; /* Chrome, Safari, Opera */
  -moz-column-width: 50px; /* Firefox */
  column-width: 50px;
  background: linear-gradient(90deg, red, yellow) left/126px 100%;
}
.time {
  -webkit-column-width: 70px; /* Chrome, Safari, Opera */
  -moz-column-width: 70px; /* Firefox */
  column-width: 70px;
  background: linear-gradient(90deg, red, yellow) right/126px 100%;
}
<table>
    <tr>
    <th>Monthly Savings</th>
    <th>Date</th>
    <th>Time</th>
    <th>Paper</th>
    <th>Pen</th>
  </tr>
  <tr>
    <td>January</td>
    <td class="date">21/1/2019</td>
    <td class="time">10:13</td>
    <td>white</td>
    <td>Black</td>
  </tr>
  <tr>
    <td>February</td>
    <td class="date">22/2/2019</td>
    <td class="time">10:23</td>
    <td>Black</td>
    <td>white</td>
  </tr>
  <tr>
    <td>March</td>
    <td class="date">3/3/2019</td>
    <td class="time">3:23</td>
    <td>blue</td>
    <td>red</td>
  </tr>
</table>

您可以轻松更改任何颜色并根据需要调整色标：

table, th, td {
  border: 1px solid black;
}
.date {
  -webkit-column-width: 50px; /* Chrome, Safari, Opera */
  -moz-column-width: 50px; /* Firefox */
  column-width: 50px;
  background: linear-gradient(90deg, red 10%, green 20%,blue 50%,pink) left/126px 100%;
}
.time {
  -webkit-column-width: 70px; /* Chrome, Safari, Opera */
  -moz-column-width: 70px; /* Firefox */
  column-width: 70px;
  background: linear-gradient(90deg, red 10%, green 20%,blue 50%,pink) right/126px 100%;
}
<table>
    <tr>
    <th>Monthly Savings</th>
    <th>Date</th>
    <th>Time</th>
    <th>Paper</th>
    <th>Pen</th>
  </tr>
  <tr>
    <td>January</td>
    <td class="date">21/1/2019</td>
    <td class="time">10:13</td>
    <td>white</td>
    <td>Black</td>
  </tr>
  <tr>
    <td>February</td>
    <td class="date">22/2/2019</td>
    <td class="time">10:23</td>
    <td>Black</td>
    <td>white</td>
  </tr>
  <tr>
    <td>March</td>
    <td class="date">3/3/2019</td>
    <td class="time">3:23</td>
    <td>blue</td>
    <td>red</td>
  </tr>
</table>
