Writing Typetura keyframes

Typetura styles are stored in CSS keyframes. Keyframe 0% is equal to a context with of 0px and keyframe 100% is equal to a context width of 1600px. Styles within each keyframe can be written as if you were styling an element.

CSS

@keyframes headline {
    0% {
        font-size: 1rem;
    }
    100% {
        font-size: 4rem;
    }
}

You can add as many keyframes as you want, using any animatable CSS property.

CSS

@keyframes headline {
    0% {
        transform: rotate(2deg);
        font-size: 1rem;
        line-height: 1.1;
        font-weight: 670;
    }
    20% {
        color: #3250a8;
    }
    50% {
        font-weight: 320;
    }
    100% {
        transform: rotate(-5deg);
        color: #1f58ff;
        font-size: 4rem;
        line-height: 1;
        font-weight: 130;
    }
}

Add as many keyframes as you wish. It is recommended that you use both a 0% and 100% keyframe. If you do not use 0% and 100% keyframes, those will default to your element styles.

Applying Typetura keyframes to an element

Now that we have our basic keyframes set up, they need to be attached to an element with the --tt-key property. These will overwrite any other layout styles so you should treat this as progressive enhancement.

CSS

@keyframes headline {
    0% {
        font-size: 1rem;
    }
    100% {
        font-size: 4rem;
    }
}

.headline {
    --tt-key: headline;
    font-size: 2.4rem;
}

Changing the maximum width

If 1600px is not the maximum width you want to style for, you can change it with --tt-max. For example, if you want the keyframe 100% to be located at 960px, then write --tt-max: 960; on your context.

CSS

@keyframes headline {
    0% {
        font-size: 1rem;
    }
    100% {
        font-size: 4rem;
    }
}

.headline {
    --tt-key: headline;
    --tt-max: 960;
    font-size: 2.4rem;
}

Transition easing

By default, Typetura uses linear easing. This means the transitions are directly proportional to the context changing. However, there are times when you want the transitions to happen slower or faster during portions of the element scaling. Easing functions enable this to happen. Apply custom easing using the --tt-ease property.

Linear interpolation vs a custom easing curve of cubic-bezier(.5,.15,.5,1)

These custom easing curves enable you to have more control over how text scales across context changes, and can reduce the number of keyframes you need.

CSS

@keyframes headline {
    0% {
        font-size: 1rem;
    }
    100% {
        font-size: 4rem;
    }
}

.headline {
    --tt-key: headline;
    --tt-ease: cubic-bezier(.5,.15,.5,1);
    font-size: 2.4rem;
}

Overwriting styles

Keyframes always overwrite element styles, even when using an !important flag. You can overwrite styles by assigning them new keyframes or removing the keyframes.

Removing Typetura keyframes

If you want to remove keyframes attached to a selector, use --tt-key: none;.

CSS

@keyframes headline {
    0% {
        font-size: 1rem;
    }
    100% {
        font-size: 4rem;
    }
}

.headline {
    --tt-key: headline;
    font-size: 2.4rem;
}
.headline.alt {
    --tt-key: none;
    font-size: 1.4rem;
}

Assigning new Typetura keyframes

Point --tt-key to a new set of keyframes you created.

CSS

@keyframes headline {
    0% {
        font-size: 1rem;
    }
    100% {
        font-size: 4rem;
    }
}
.headline {
    --tt-key: headline;
    font-size: 2.4rem;
}

@keyframes headline-alt {
    0% {
        font-size: 0.9rem;
    }
    100% {
        font-size: 2.2rem;
    }
}
.headline.alt {
    --tt-key: headline-alt;
    font-size: 1.2rem;
}
