Layout: cheat sheet

<img> image

A picture. src is the picture file; alt describes it for people who cannot see it. There is no closing tag.

<img src="trophy.svg" alt="A gold trophy">

Example

<img src="medal.svg" alt="A silver medal" width="100">
<p>Second place</p>

What it draws — The picture, 100 pixels wide

gap

Space between the items in a flex row (on the parent, with display: flex).

gap: 16px;

Example

<style>
  .row {
    display: flex;
    gap: 40px;
  }
</style>
<div class="row">
  <p>One</p>
  <p>Two</p>
  <p>Three</p>
</div>

list-style

Remove the bullets or numbers from a list: menus are lists without bullets.

list-style: none;

Example

<style>
  ol {
    list-style: none;
  }
</style>
<ol>
  <li>First</li>
  <li>Second</li>
</ol>

display: flex

Put it on the box that holds the items (the parent): its children line up in a row.

display: flex;

Example

<style>
  .row {
    display: flex;
  }
</style>
<div class="row">
  <p>One</p>
  <p>Two</p>
  <p>Three</p>
</div>

flex-wrap

Let items move to the next line when the row is full.

flex-wrap: wrap;

Example

<style>
  .row {
    display: flex;
    flex-wrap: wrap;
    gap: 8px;
    width: 180px;
  }
</style>
<div class="row">
  <img src="star.svg" alt="Star" width="50">
  <img src="star.svg" alt="Star" width="50">
  <img src="star.svg" alt="Star" width="50">
  <img src="star.svg" alt="Star" width="50">
</div>

alt text

Says what a picture shows, for anyone who can't see it (screen readers read it aloud). Use alt="" for a picture that is only decoration.

<img src="trophy.svg" alt="A gold trophy">

relative path

A file name with no folder means "beside this page"; images/trophy.svg means "in the images folder beside this page". Never a path from your own computer (C:/Users/…).

<img src="trophy.svg" alt="…">
<link rel="stylesheet" href="style.css">
