Font properties

After you’ve added your fonts, you may have noticed that after changing --blokks-default-font, some properties, for example font-size, need adjusting.

Font scaling

Blokks uses em units to define its font sizes. This means that all sizes are relative to its parent element, which in our case is the embed root. So, to change all font-sizes at once you can simply set the --blokks-font-scale variable:

:root {
  /* This scales all fonts by 1.5 */
  --blokks-font-scale: 150%;

  /* You can also use other units like px and pt*/
  --blokks-font-scale: 32px;
  --blokks-font-scale: 16pt;

Alternatively, you can set the font-size property on the embed root directly:

.blokks {
  /* Scaling using percentages */
  font-size: 150%;

  /* Or using absolute numbers */
  font-size: 32px;
  font-size: 16pt;

Sometimes the result of using the --blokks-font-scale variable may differ from what you expect. This is caused when using relative scaling in combination with the cascading nature of CSS. To fix this, use absolute values for scaling, like px or pt.

Other properties

Font properties inherit its values from parent elements. So setting letter-spacing: 1px; on the embed root will automatically set the letter-spacing on all text elements in the embed.

If you want to target individual elements we need to target the text with CSS selectors. Grab the class name of the element you’ve selected (in our case this is .blokks-location__title) and add it to the CSS of your page. For example, let’s make it bold, underline and italic. Also, let’s make the font size bigger:

.blokks-location__title {
  font-size: 18px;
  font-weight: 700;
  font-style: italic;
  text-decoration: underline;

Like CSS variables all CSS classnames start with .blokks- to avoid naming conflicts. But sometimes some of your existing website’s styling will accidentally be used by the embed. Read more here on how to solve this.

Note: the order in which CSS rules are stated determines which ones take precedence: “CSS rules that appear later in the code override earlier rules if both have the same specificity.” Basically this means that you should add the <style> tag after the Blokks import. For example:

<!-- Link to the Blokks theme -->
<link href='schedule.css' rel='stylesheet' media=‘screen’>

<!-- Add your own styling -->
  .blokks-location__title {
    font-size: 2em;
    font-weight: 700;
    font-style: italic;
    text-decoration: underline;

<!-- Or link to your own stylesheet -->
<link href='custom.css' rel='stylesheet' media=‘screen’>
