How to select all elements whose ID starts and ends with specific strings?
提问by Danny Beckett
In CSS, how can I select all <tr>elements where their idbegins with section_and ends with _dummy?
在 CSS 中,如何选择<tr>以id开头section_和结尾的所有元素_dummy?
E.g. I'd like to select and apply styles the following <tr>s:
例如,我想选择并应用以下样式<tr>:
<tr id="section_5_1_dummy">
<td>...</td>
</tr>
<tr id="section_5_2_dummy">
<td>...</td>
</tr>

The following CSS3 selector will do the job:
以下 CSS3 选择器将完成这项工作:
tr[id^="section_"][id$="_dummy"] {
height: 200px;
}
The ^denotes what the idshould begin with.
该^表示什么id应该开始。
The $denotes what the idshould end with.
该$表示什么id应该结束。
iditself can be replaced with another attribute, such as href, when applied to (for example) <a>:
id本身可以替换为另一个属性,例如href,当应用于(例如)时<a>:
a[href^="http://www.example.com/product_"][href$="/about"] {
background-color: red;
}
