How to get href from an element from sibling class search?

I would like to get the href from the following html

<a class="AirQuality--detailsButton--DBdLS Button--primary--1UQTP" href="/en-IN/forecast/air-quality/l/bf01d09009561812f3f95abece23d16e123d8c08fd0b8ec7ffc9215c0154913c" target="_self">See Details</a>

where href to be extracted based on class class="AirQuality--detailsButton--DBdLS Button--primary--1UQTP" from element a.

I tried doing the following but not returning anything.

response.css('a.AirQuality--detailsButton--DBdLS Button--primary--1UQTP::attr(href)').get()

Full html could be fetched through scrapy by

scrapy shell "https://weather.com/en-IN/weather/today/l/bf01d09009561812f3f95abece23d16e123d8c08fd0b8ec7ffc9215c0154913c"

Any help would be highly appreciated, thanks in advance 🙂

>Solution :

There are two class name . so you need to add dot(.) .Now it’s working.

response.css('a.AirQuality--detailsButton--DBdLS.Button--primary--1UQTP::attr(href)').get()
