The following CSS3 selector will do the job:
tr[id^="section_"][id$="_dummy"] {
height: 200px;
}
The ^
denotes what the id
should begin with.
The $
denotes what the id
should end with.
id
itself can be replaced with another attribute, such as href
, when applied to (for example) <a>
:
a[href^="http://www.example.com/product_"][href$="/about"] {
background-color: red;
}
