| Static Files | |
| ============ | |
| The authentication views and templates work, but they look very plain | |
| right now. Some `CSS`_ can be added to add style to the HTML layout you | |
| constructed. The style won't change, so it's a *static* file rather than | |
| a template. | |
| Flask automatically adds a ``static`` view that takes a path relative | |
| to the ``flaskr/static`` directory and serves it. The ``base.html`` | |
| template already has a link to the ``style.css`` file: | |
| .. code-block:: html+jinja | |
| {{ url_for('static', filename='style.css') }} | |
| Besides CSS, other types of static files might be files with JavaScript | |
| functions, or a logo image. They are all placed under the | |
| ``flaskr/static`` directory and referenced with | |
| ``url_for('static', filename='...')``. | |
| This tutorial isn't focused on how to write CSS, so you can just copy | |
| the following into the ``flaskr/static/style.css`` file: | |
| .. code-block:: css | |
| :caption: ``flaskr/static/style.css`` | |
| html { font-family: sans-serif; background: #eee; padding: 1rem; } | |
| body { max-width: 960px; margin: 0 auto; background: white; } | |
| h1 { font-family: serif; color: #377ba8; margin: 1rem 0; } | |
| a { color: #377ba8; } | |
| hr { border: none; border-top: 1px solid lightgray; } | |
| nav { background: lightgray; display: flex; align-items: center; padding: 0 0.5rem; } | |
| nav h1 { flex: auto; margin: 0; } | |
| nav h1 a { text-decoration: none; padding: 0.25rem 0.5rem; } | |
| nav ul { display: flex; list-style: none; margin: 0; padding: 0; } | |
| nav ul li a, nav ul li span, header .action { display: block; padding: 0.5rem; } | |
| .content { padding: 0 1rem 1rem; } | |
| .content > header { border-bottom: 1px solid lightgray; display: flex; align-items: flex-end; } | |
| .content > header h1 { flex: auto; margin: 1rem 0 0.25rem 0; } | |
| .flash { margin: 1em 0; padding: 1em; background: #cae6f6; border: 1px solid #377ba8; } | |
| .post > header { display: flex; align-items: flex-end; font-size: 0.85em; } | |
| .post > header > div:first-of-type { flex: auto; } | |
| .post > header h1 { font-size: 1.5em; margin-bottom: 0; } | |
| .post .about { color: slategray; font-style: italic; } | |
| .post .body { white-space: pre-line; } | |
| .content:last-child { margin-bottom: 0; } | |
| .content form { margin: 1em 0; display: flex; flex-direction: column; } | |
| .content label { font-weight: bold; margin-bottom: 0.5em; } | |
| .content input, .content textarea { margin-bottom: 1em; } | |
| .content textarea { min-height: 12em; resize: vertical; } | |
| input.danger { color: #cc2f2e; } | |
| input[type=submit] { align-self: start; min-width: 10em; } | |
| You can find a less compact version of ``style.css`` in the | |
| :gh:`example code <examples/tutorial/flaskr/static/style.css>`. | |

| You can read more about CSS from `Mozilla's documentation <CSS_>`_. If | |
| you change a static file, refresh the browser page. If the change | |
| doesn't show up, try clearing your browser's cache. | |
