Specify many grid properties at once with the grid shorthand

4:09 css

Using the grid shorthand property, we can set all of the explicit grid properties (grid-template-rows, grid-template-columns, and grid-template-areas), all the implicit grid properties (grid-auto-rows, grid-auto-columns, and grid-auto-flow), and the gutter properties (grid-column-gap and grid-row-gap) in a single declaration.

2:10 css

What about the situation in which we aren’t specifying the number of columns or rows to be repeated? There are two properties we can use in this situation; auto-fill and auto-fit. We’ll explore what each one does and why we would need to use them on our grid-tracks.

css tutorial about Nest a grid within a grid

css tutorial about Change the auto-placement behaviour of grid items with grid-auto-flow

Change the auto-placement behaviour of grid items with grid-auto-flow

2:39 css

We can change the automatic behaviour of what order our grid items appear. We can even re-order the items in our grid to fill available space using the dense keyword. How do we approach this using grid-auto-flow?

css tutorial about Use the repeat function to efficiently write grid-template values

Use the repeat function to efficiently write grid-template values

3:14 css

We can use the repeat() function if we have repeating specifications for columns and rows. With the minmax() function, we can define a size range for our grid items. Let’s see how to apply these properties, and how it affects the behaviour of our grid layout.

There’s an unfamiliar fr unit pertinent to CSS Grid, which allows us to specify a fractional unit of space. Let’s see how to apply it.

css tutorial about Place grid items on a grid using grid-column and grid-row

Place grid items on a grid using grid-column and grid-row

3:13 css

It’s possible to position a grid item anywhere on a grid track. To do this, let’s specify some grid-template-columns and grid-template-rows, and to the grid items, we’ll pass grid-column and grid-row some numeric values.

Hello SCSS maps and the @each control directive! In this lesson, we’ll check out iterating with lists and looping over data sets with maps and the @each directive.

css tutorial about Style an SVG Icon with CSS

Style an SVG Icon with CSS

3:17 css PRO

In this lesson, you’ll learn how to create interactive and multi-colored SVG icons using only CSS. You’ll also see how the same familiar rules of inheritance and specificity apply when working with SVG. We’ll style icons on hover, change their size and style individual parts of an icon.

When implementing SVG icons with the use tag, the browser renders the SVG inside something called the "shadow dom". Unfortunately, most browsers do not support accessing child elements of the shadow dom via CSS. In order to target elements inside a use tag, such as a path, you can target it at the global CSS level, like so:

path#rain {
/* styles */
}

Instead of:

.Icon--umbrella path#rain {
  /* styles */
}
css tutorial about Automate SVG Sprite Background Image Variations with a SCSS Mixin

Automate SVG Sprite Background Image Variations with a SCSS Mixin

4:12 css PRO

n this lesson, you’ll learn how to write a SCSS mixin to generate styles for variations of background-images. We’ll look at using SCSS lists to interpolate dynamic class names and property attributes and output icons at different sizes.

If you need the ability to add or edit icons on a regular basis, having a SCSS mixin do the heavy lifting of calculating background-position, background-size and creating selectors will save you lots of time and manual work.

Note: this lesson assumes you have an understanding of SCSS, mixins and already have a process to compile SCSS.

css tutorial about Get up and running with CSS Grid Layout

Get up and running with CSS Grid Layout

2:15 css

css tutorial about Describe a grid layout using named grid lines

Describe a grid layout using named grid lines

css tutorial about Reuse Flexbox Styles With A Sass Mixin

Reuse Flexbox Styles With A Sass Mixin

0:58 css

You can target an element that has no child elements by using the :empty pseudo-class. With browser support down to IE9, it's solid, easy way to select empty elements without any additional markup.

Be aware that whitespace is considered a "child", so :empty will not work if the element has no children, but has space between the opening and closing tags.

css tutorial about Create a fixed-fluid-fixed layout using CSS calc()

Create a fixed-fluid-fixed layout using CSS calc()

0:59 css

CSS calc() allows you to mix and match units to get real-time calculations. It's useful when you need to size elements but you have some unknown number that you have to account for.

css tutorial about Layout Responsive Fluid Columns Using CSS

Layout Responsive Fluid Columns Using CSS

3:03 css

Learn how to use CSS columns to quickly lay out fluid columns that are responsive, degrade gracefully and don't require extra markup.

Notes:

  • column-width operates like min-width, not width. The browser will render as many columns as it can with the width provided. If each column can take up more than the value provided, they will do so.
  • column-span enables a specific element to ignore column-count and column-width. It can be set to an integer to span a certain number of columns, or "all" to span them all. However, this property does not work in Firefox. A workaround could be to move the element (say, a heading) outside of the container with the columns applied to it. That way, it remains outside of the automatic column flow.
  • column-fill allows you to change the way content flows into columns. By default, it's set to "balance", where content is distributed as much as possible between columns. It can also be set to "auto", but in order to do so, it requires setting a fixed height. This breaks the idea of fluid, responsive layouts, so use it with caution. You'll also need some browser prefixes, so be sure to reference this browser support chart.

Focus management using CSS, HTML, and JavaScript

8:34 css

Something important to consider when coding a web application is managing the user's focus.
