o-arc Custom Element

<o-arc> is a standard and vanilla web-component for rendering a radial arcs or pies. By default there are up to 60 arcs elements per orbit.

Look and feel

Changing arc colors

To change o-arc color use CSS custom var --o-arc-color and --o-hover-arc-color in a o-arc style.


o-arc.cyan {
--o-arc-color: var(--o-cyan-light);
--o-hover-arc-color: var(--o-cyan)
}
o-arc.purple {
--o-arc-color: var(--o-purple-light);
--o-hover-arc-color: var(--o-purple)
}
o-arc:hover{
cursor: pointer
}
o-arc {
--o-gap: 1; /* This will be added as default soon*/
}

Changing endings

o-arc has one special attribute: shape to define different endings. Currently, you can choose between circle, arrow, slash, backslash and zigzag shapes. Default none.

Adjust o-arc size

Each o-arc has one orbit space size, but it can be finely adjusted using the CSS class utility .shrink-10 to .shrink-90, allowing the vectors to shrink by a specified percentage.



.orbit-5 {
border: 1px dashed var(--o-cyan);
}
o-arc {
--o-gap: 1; /* This will be added as default soon*/
}

      <o-arc class="shrink-90" style="--o-arc-color: var(--o-orange)"></o-arc>

.orbit-5 {
border: 1px dashed var(--o-cyan);
}
o-arc {
--o-gap: 1; /* This will be added as default soon*/
}

On opposite way, the CSS class utility .grow-0x to .grow-12x, allowing vector to expand by a multiple of .orbit size. It is possible to use decimal fractions. For example, .grow-0.1x, .grow-10.7x, etc.


.satellite {
border: none;
}
.orbit-5 {
border: 1px dashed var(--o-cyan);
}

}

Adjust o-arc gaps

.gap-*: Set a gap space between o-arcs ranging from 0 to 30,


.satellite {
border: none;
}
.orbit-5 {
border: 1px dashed var(--o-cyan);
}

o-arc {
--o-gap: 1; /* This will be added as default soon*/

Adjusting radial layout

Arbitrary o-arc angle.

.angle-*: Set starting point angle from 0 to 360 degrees, overrriding automatic radial arragement.

.orbit-5 {

o-arc {

Relative o-arc orbital position

By default, o-arc is positioned in the middle of orbit path. To change that, there some CSS utilities:

.inner-orbit: To place ano-arc just below its orbit.

.outer-orbit: To place o-arc just above its orbit.

.quarter-inner-orbit: To place o-arc a 25% into its orbit.

.quarter-outer-orbit: To place o-arc a 25% outer its orbit.
