+
+Flexbox is a one-dimensional CSS layout that can control the way items are spaced out and aligned within a container.
+
+To use it, give an element a `display` property of `flex`. This will make the element a <em>flex container</em>. Any direct children of a flex container are called <em>flex items</em>.
+
+Create a `.gallery` selector and make it a flex container.
+
+
+
+# --hints--
+
+You should have a `.gallery` selector.
+
+```js
+assert.exists(new __helpers.CSSHelp(document).getStyle('.gallery'));
+```
+
+Your `.gallery` selector should have a `display` property set to `flex` as the value.
+
+```js
+assert.equal(new __helpers.CSSHelp(document).getStyle('.gallery')?.display, 'flex');
+```

+Flexbox has a main and cross axis. The main axis is defined by the `flex-direction` property, which has four possible values:
+
+- `row` (default): horizontal axis with flex items from left to right
+- `row-reverse`: horizontal axis with flex items from right to left
+- `column`: vertical axis with flex items from top to bottom
+- `column-reverse`: vertical axis with flex items from bottom to top
+
+**Note**: The axes and directions will be different depending on the text direction. The values shown are for a left-to-right text direction.
+
+Try the different values to see how they affect the layout.
+
+When you are done, set an explicit `flex-direction` of `row` on the `.gallery` element.
+
+# --hints--
+
+Your `.gallery` selector should have a `flex-direction` property set to `row` as the value.
+
+```js
+assert(new __helpers.CSSHelp(document).getStyle('.gallery')?.flexDirection === 'row');

+The `flex-wrap` property determines how your flex items behave when the flex container is too small. Setting it to `wrap` will allow the items to wrap to the next row or column. `nowrap` (default) will prevent your items from wrapping and shrink them if needed.
+
+
+Make it so your flex items wrap to the next row when they run out of space.
+
+# --hints--
+
+Your `.gallery` selector should have a `flex-wrap` property set to `wrap` as the value.

+
+Notice how some of your images have become distorted. This is because the images have different aspect ratios. Rather than setting each aspect ratio individually, you can use the `object-fit` property to determine how images should behave.
+
+Give your `.gallery img` selector the `object-fit` property and set it to `cover`. This will tell the image to fill the `img` container while maintaining aspect ratio, resulting in cropping to fit.
+
+# --hints--
+
+Your `.gallery img` selector should have an `object-fit` property set to `cover` as the value.
+
+```js
+assert(new __helpers.CSSHelp(document).getStyle('.gallery img')?.objectFit === 'cover');
+```

+Your images need some space between them.
+
+The `gap` CSS shorthand property sets the gaps, also known as gutters, between rows and columns. The `gap` property and its `row-gap` and `column-gap` sub-properties provide this functionality for flex, grid, and multi-column layout. You apply the property to the container element.
+
+Give your `.gallery` flex container a `gap` property with `16px` as the value.
+
+# --hints--

+
+The `::after` pseudo-element creates an element that is the last child of the selected element. You can use it to add an empty element after the last image. If you give it the same `width` as the images it will push the last image to the left when the gallery is in a two-column layout. Right now, it is in the center because you set `justify-content: center` on the flex container.
+
+Example:
+
+```CSS
+.container::after {
+  content: "";
+  width: 860px;
+}
+```
+
+Create a new selector using an `::after` pseudo-element on the `.gallery` element. Add a `content` property set to an empty string `""` and `350px` set for the `width` property.
+
+# --hints--
+
+Your `.gallery::after` selector should have an empty string `""` set for the `content` property.
+
+```js
+assert(new __helpers.CSSHelp(document).getStyle('.gallery::after')?.content === "\"\"");
+```
+
+Your `.gallery::after` selector should have `350px` set for the `width` property.
+
+```js
+assert(new __helpers.CSSHelp(document).getStyle('.gallery::after')?.width === "350px");

+The `alt` image attribute should describe the image content. Screen readers announce the alternative text in place of images. If the image can't be loaded, this text is presented in place of the image.

+To complete the project, add an `alt` attribute to all nine of your cat images to describe them. Use a value at least five characters long for each.
+
+
+# --hints--

+All nine of your `img` elements should have a `alt` attribute with text describing each image, with each description using at least `5` letters.

+The `border-box` sizing model does the opposite of `content-box`. The total width of the element, including padding and border, will be the explicit width set. The content of the element will shrink to make room for the padding and border.
+
+Change the `box-sizing` property to `border-box`. Notice how your blue image borders now fit within your red gallery border.
+
+# --hints--

+
+Your * selector should have a `box-sizing` property set to `border-box` as the value.

+
+Notice how the blue image border extends beyond the red gallery border. This is due to the way browsers calculate the size of container elements.
+
+The `box-sizing` property is used to set this behavior. By default, the `content-box` model is used. With this model, when an element has a specific width, that width is calculated based only on the element's content. Padding and border values get added to the total width, so the element grows to accommodate these values.
+
+Try setting `box-sizing` to `content-box` explicitly, with the global `*` selector. At this point, you will not see any changes, because you are using the default value.
+
+# --hints--
+
+You should have a `*` selector.
+
+```js
+assert.exists(new __helpers.CSSHelp(document).getStyle('*'));
+```
+
+Your `*` selector should have a `box-sizing` property.
+
+```js
+assert.exists(new __helpers.CSSHelp(document).getStyle('*')?.boxSizing);
+```
+
+Your `*` selector should have its `box-sizing` property set to `content-box`.

+In order to better visualize how your elements are sized, adding a border can be helpful.
+
+Give your `.gallery` element a `width` of `50%` and a `border` set to `5px solid red`.
