### Build selectors with appropriate specificity

Selectors that are too general might sweep up unexpected elements.
When possible, select the first parent tag and then specify the desired element within that selection.

**Why?** Elements that are overly specific are less flexible and may fail if unexpected DOM changes occur. It also reduces the amount of the DOM it needs to parse.

<span style="color:green">
GOOD:
</span>

```html
form[name='myform'] > input[name='firstname']

//*[@id='container'][@class='dashboard-title']
```

<span style="color:red">
BAD:
</span>

```html
input[name='firstname']

//*[@id='container']/*[@class='dashboard-advanced-reports']/*[@class='dashboard-advanced- reports-description']/*[@class='dashboard-title']
```
