Question: How can you select the first and the last `TD` in a row?

```
tr > td[0],
tr > td[-1] {
/* styles */
}

```

Answer: 
You could use the **:first-child** and **:last-child** `pseudo-selectors`:

```
tr td:first-child{
    color:red;
}
tr td:last-child {
    color:green
}

```

Or you can use other way like

```
// To first child 
tr td:nth-child(1){
    color:red;
}

// To last child 
tr td:nth-last-child(1){
    color:green;
}

```

Both way are perfectly working
You can use

table tr td:first-child { css here
}
**for First Child and**

table tr td:last-child { css here
}
**for last Child**.
