CBCA - CSS with Flexbox (Intermediate)-01.jpg

In this course, you will get hands-on experience in designing mobile-responsive web layouts using Flexbox. You will start with the basics like the Box Model and the process of layouting.

You will then move on to advanced concepts such as Flexbox containers, and aligning individual Flexbox items. Near the end of the course, you will put everything you just learned into practice. You will work on a project that focuses on developing a mobile-first website where you’ll experiment with page layout, headers, footers, and a lot more.

By the end of this course, you will be able to use Flexbox in your own projects to create beautiful layouts.

Designing Web Layouts with CSS and Flexbox

# Blog post thumbnail, title, and summary

Each blog post will receive identical content. 

We will use an online placeholder service to generate placeholder images for the thumbnails. We will use the link `/udata/WPVy7kaW8e6/720x480.png` to generate an image.

Each blog post will have a thumbnail, an `h3` heading, and one paragraph. These items will be displayed below each other.

```html
<div class="blogpost">
  <img
    src="/udata/WPVy7kaW8e6/720x480.png" 
    alt="placeholder image"
    class="blogpost-thumbnail" />
  <h3>First post</h3>
  <p>This is an example post.</p>
</div>
```

Technically, we could use Flexbox with `flex-direction: column;` to position the Flex items below each other. However, similar to the main banner, this makes little sense, as block-level elements are already positioned below each other, and we can freely set their margins.

Therefore, this lesson gives you another example, where using Flexbox is suboptimal.

To style the blog post, let's add a `20px` padding inside the container, around the thumbnail, the title, and the paragraph. This does not change the dimensions of the blog post, because of the global `border-box` setting for all elements.

We also have to set the thumbnail image's width to stay proportionally sized inside the Flexbox container by adding a `width: 100%` rule. We can also set a `10px` vertical margin around the title and the paragraph.

```css
.blogpost {
  min-height: 100px;
  border: 1px solid black;
  padding: 20px;
}

.blogpost-thumbnail {
  width: 100%;
}

.blogpost-title, .blogpost-preview {
  margin: 10px 0;
}
```

We are done with the blog post styling:
