# Bootstrap Components and Utilities

Bootstrap provides many utilities and components you can use when customizing Evennia’s web presence. We’ll go over a few examples here that you might find useful.

> Please take a look at either the basic web tutorial or the web character view tutorial to get a feel for how to add pages to Evennia’s website to test these examples.

## General Styling

Bootstrap provides base styles for your site. These can be customized through CSS, but the default styles are intended to provide a consistent, clean look for sites.

### Color

Most elements can be styled with default colors. Take a look at the documentation to learn more about these colors

- suffice to say, adding a class of text-* or bg-*, for instance, text-primary, sets the text color or background color.

### Borders

Simply adding a class of ‘border’ to an element adds a border to the element. For more in-depth info, please read the documentation on borders..

    <span class="border border-dark"></span>

You can also easily round corners just by adding a class.

    <img src="..." class="rounded" />

### Spacing

Bootstrap provides classes to easily add responsive margin and padding. Most of the time, you might like to add margins or padding through CSS itself - however these classes are used in the default Evennia site. Take a look at the docs to learn more.

## Components

### Buttons

Buttons in Bootstrap are very easy to use - button styling can be added to `<button>`, `<a>`, and `<input>` elements.

    <a class="btn btn-primary" href="#" role="button">I'm a Button</a>
    <button class="btn btn-primary" type="submit">Me too!</button>
    <input class="btn btn-primary" type="button" value="Button">
    <input class="btn btn-primary" type="submit" value="Also a Button">
    <input class="btn btn-primary" type="reset" value="Button as Well">

### Cards

Cards provide a container for other elements that stands out from the rest of the page. The “Accounts”, “Recently Connected”, and “Database Stats” on the default webpage are all in cards. Cards provide quite a bit of formatting options - the following is a simple example, but read the documentation or look at the site’s source for more.

    <div class="card">
      <div class="card-body">
        <h4 class="card-title">Card title</h4>
        <h6 class="card-subtitle mb-2 text-muted">Card subtitle</h6>
        <p class="card-text">Fancy, isn't it?</p>
        <a href="#" class="card-link">Card link</a>
      </div>
    </div>

### Jumbotron

Jumbotrons are useful for featuring an image or tagline for your game. They can flow with the rest of your content or take up the full width of the page - Evennia’s base site uses the former.

    <div class="jumbotron jumbotron-fluid">
      <div class="container">
        <h1 class="display-3">Full Width Jumbotron</h1>
        <p class="lead">Look at the source of the default Evennia page for a regular Jumbotron</p>
      </div>
    </div>

### Forms

Forms are highly customizable with Bootstrap. For a more in-depth look at how to use forms and their styles in your own Evennia site, please read over the web character gen tutorial.
