Answer 1

No, that's about right

<section class="blog">
  <div class="container">
    <div class="blog__headline">
      <h2 class="blog__title">Recent blog</h2>
      <p class="blog__subtitle">Donec nulla justo, pharetra in nulla in, lacinia pulvinar nunc. Nunc rutrum nisi vel nibh cursus, nec vestibulum orci feugiat.</p>
    </div>
    <div class="blog__posts">
      <div class="post">
        <img class="post__img" src="img/blog2.png">
        <h3 class="post__title">Is there hope for the SEO profession?</h3>
        <span class="post__author">Post by Lawrence R. Smith</span>
        <p class="post__description">Donec nulla justo, pharetra in nulla in, lacinia pulvinar nunc. Nunc rutrum nisi vel nibh cursus, nec vestibulum orci feugiat. Nunc in luctus lacus. Integer eget dui nisi. Integer mauris lacus.</p>
        <a class="button post__button" href="#">Read More</a>
      </div>
    </div>
    <a class="button blog__button" href="#">+ load more</a>
