Configuration specific to HTML format

Prerequisites

Dokka's Html format requires a web server to view documentation correctly. This can be achieved by using the one that is build in IntelliJ or providing your own. If this requisite is not fulfilled Dokka with fail to load navigation pane and search bars.

!!! important Concepts specified below apply only to configuration of the Base Plugin (that contains Html format) and needs to be applied via pluginsConfiguration and not on the root one.

Modifying assets

It is possible to change static assets that are used to generate dokka's HTML. Currently, user can modify:

  • customAssets
  • customStyleSheets

Every file provided in those values will be applied to every page.

Dokka uses 3 stylesheets:

  • style.css - main css file responsible for styling the page
  • jetbrains-mono.css - fonts used across dokka
  • logo-styles.css - logo styling

User can choose to add or override those files. Resources will be overridden when in pluginConfiguration block there is a resource with the same name.

Modifying footer

Dokka supports custom messages in the footer via footerMessage string property on base plugin configuration. Keep in mind that this value will be passed exactly to the output html, so it has to be valid and escaped correctly.

Separating inherited members

By setting a boolean property separateInheritedMembers dokka will split inherited members (like functions, properties etc.) from ones declared in viewed class. Separated members will have it's own tabs on the page.

Merging declarations with name clashing

By setting a boolean property mergeImplicitExpectActualDeclarations dokka will merge declarations that do not have expect/actual keywords but have the same fully qualified name. The declarations will be displayed on one page. By default, it is disabled. The page names of such declaration have a prefix that is the name of source set.

Examples

In order to override a logo and style it accordingly a css file named logo-styles.css is needed:

.library-name a {
    position: relative;
    --logo-width: 100px;
    margin-left: calc(var(--logo-width) + 5px);
}

.library-name a::before {
    content: '';
    background: url("https://upload.wikimedia.org/wikipedia/commons/9/9d/Ubuntu_logo.svg") center no-repeat;
    background-size: contain;
    position: absolute;
    width: var(--logo-width);
    height: 50px;
    top: -18px;
    left: calc(-1 * var(--logo-width) - 5px);
    /* other styles required to make your page pretty */
}
