My scrapy not working for extracting html links

The code I've written for scraping and following links is not working for some reason. It doesn't follow the links in the page and returns only the 1st page results. Below is the code for reference

import scrapy

class LabnolSpider (scrapy.Spider):
name = "labnolblog"
start_urls = ['https://www.labnol.org/',
]

def parse (self, response):
    for blog in response.css ('div.feature__body'):
        yield {
            'Title' : blog.css ('div.feature__body h2::text').extract(),
            'Date' : blog.css ('div.feature__body p::text').extract(),
        }
    #for a in response.css ('a.btn btn--primary xtype--uppercase a::attr(href)'):
     #   yield response.follow (a, self.parse)

    next_page = response.css ('.a.btn btn--primary xtype--uppercase a::attr(href)').extract()
    if next_page is not None:
         yield response.follow (next_page, callback = self.parse)
         #next_page = response.urljoin (next_page)
         #yield scrapy.Request (next_page, callback = self.parse)

def parse_blogs (self, response):
    def extract_with_css (query):
        return response.css (query).extract_first().strip()
        yield {
            'Title' : extract_with_css('.h2.home__title::text()'),
            'Date' : extract_with_css ('.p.home__date::text'),
        }
