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

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

```

Answer: 
If the row contains some leading (or trailing) `th` tags before the `td` you should use the `:first-of-type` and the `:last-of-type` selectors. Otherwise the first `td` won't be selected if it's not the first element of the row. 

This gives: 

```
td:first-of-type, td:last-of-type {
    /* styles */
}

```
You can use

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

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