About blockstart.css

The blockstart.css file gives you a simple set of basic layout primitives to get started. It allows you to follow a process similar to painters:

1. Organize the big "gross" structure without details in monochrome.
2. Develop a first statement with a meaningful structure and a simplified monochrome design.
3. Refine a second statement by filling in the structure with content and additional refinements for that content.
4. Complete a third statement with further refined details, fonts, and color schemes.

In practical terms this means:

1. Use blockstart.css to get a "chunky" boxes and grids layout.
2. Replace the blockstart.css with semantic HTML tags and your own CSS, adding first refinements.
3. Fill in your blocks with media so you have something to design around that's real, refining further.
4. Develop this last stage of the design with font choices, color, and other details that fit the content.

The blockstart.css file helps with this process by giving you the minimum necessary blocks to create the first statement. There is almost nothing in the CSS, making it easy to replace in later stages...if you want.

Blocks

The <block> is the main structure. It's a block. When you put things in it, they stay in there. That's how a block should work:

Debugging

Not sure where the boxes are? Add class="debug" to the block (or grid) and it will put a red border around the outer box, then a blue border around the children:

Blocks Propagate

The first children in a block become a blocks too. In the beginning that's usually what you want. This means you don't need to put blocks inside blocks unless you want to. You can remove this on an element with class="no-flex":

In that example, the "No Flex" lines are spaced normally because the code has class="no-flex" on that block.

Solid Blocks

You can make a block solid with class="solid"

Notice how it takes up the whole page? Notice how it is monochrome? That's all you need. You can change the "value" of a solid block with a variable style="--value: 3":

We can't read that text so we need something called a "Value."

Values

What's a value? A value represents a simple number for the "light" and "dark" of something. Think of it as a measure of the amount of light produced. A value 9 object gives off a lot of light, so it's white. A value 0 object gives off no light, so it's black. You can do most initial designs with only 5 values, but blockstart.css has 10 (0-9) to help with contrast. You can usually change the background with --value: 0 and the text with --text: 9 in most places.

We can fix that last block's contrast with value 9 text using style="--text: 9;":

If we use style="--value: 0; --text: 9;" we can get a high contast dark block:

Values make it easier to solve contrast in your designs because you don't have to think about thousands of colors and their luminance levels. Just make the difference in value between your text (the subject) and background (the ground) to increase contrast. In the previous block the difference was 9 because background is value 0 and text is value 9.

Shapes

You always need some kind of rectangle shape to represent where a photo might go, and the shape tag handles that:

You set the shape's size with style="--w: 300px; --h: 300px;".

Padding

Just add class="pad" to give a simple 1rem padding to a block. Use the variable style="--pad: 1rem" to change its padding.

Borders

Things need borders and you can add a border with class="border":

Center

Many times in the beginning you'll want to say something is centered, and you mean the whole thing, not just randomly the box but not its content. Add class="center" and it will be centered:

Notice the text isn't centered, because many times you don't want centered text. On landing pages it seems that everything is centered, so you can add center-text to also center the text. You can place this on anything too, not just blocks:

You can also add class="center-self" on elements that you want to center but not really the contents, and when it's not explicitly a block tag but you want it centered.

Patterns

Sometimes you need a little indicator for a block to make it different for later changes. You can use three patterns of stripes, lines, and dots.

You can change the line/dot/stripe color with --pat-val, and combine it with the block background setting --value. For example, these are all white patterns on black blocks:

Horizontal

By default blocks are vertical, like a web page, because blocks being horizontal by default is stupid. You can make a block horizontal with class="horizontal", and then make it vertical again with class="vertical". Here's a side-by-side block using horizontal:

Spacer

You can add a basic spacing between blocks with <hr> tags. The line is hidden.

Grids

You can make a grid, and it'll actually be a grid, that contains its contents. Amazing. Your boxes can also have solid backgrounds or dots, stripes, and lines.

You set the rows, columns, and gap with style variables --rows, --columns, and --gap like so:

<grid style="--rows: auto; --cols: 1fr 1fr 1fr; --gap: 1rem;">

Here is that grid setting using blocks inside for each of the patterns:

Stacked Layers

Frequently you need to use multiple layers as in an image with text on top. You might not need this in the layout phase, but in the first statement it does come up. The stack tag will position all of it's children on top of each other in order, and you can set one as the top with class="top".

In this demo I have a block with "I'm on Bottom" that I cover with another block that uses a stripes pattern. This gives the effect of putting the text behind bars. Remember that these stack in the reverse order you write them, unless you tag one with class="top".

I put class="debug" around the "I'm on Top" class so you can see where it gets placed. The "top" block has the lines and you can read the text clearly. The "I'm on Bottom" text is hiding behined these lines.

Content

Many times you want one section to take up the whole page width, but then content under that to be padded. You can just manually set the width most of the time, or use the content tag. Add on the class="pad" to give it padding, or class="sized" to set its width or height.

Getting Started

Once you download the blockstart.css you need a web server. For people who use Node.js you can run the http-server package to get a simple one. Here's the commands that I use to get a project started:

mkdir myproject
cd myproject
npm init
# Answer all the questions
npm install http-server
mkdir public
npx http-server -d -c-1 public

Once you do that you can place the blockstart.css in the public/ directory and start putting your .html files in the same place. Here's a decen starter template:

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <title>Blockstart Template</title>
  <link rel="stylesheet" href="/blockstart.css">
<style>
</style>
</head>
<body>
</body>
</html>

There's a lot you can add to an HTML page to make it work on different platforms, including all the icons ever invented by Apple, but this file gets you started when using the blockstart.css.
