Question

Include an additional feature to an already established design

I have been attempting to move an element to the left using the transform property. However, there is already a pre-existing style with transform, which appears as:

transform: translate3d(tx, ty, tz)

What I am aiming for is to incorporate another property alongside translate3d(tx, ty, tz), known as translateX(tx). Therefore, the complete style would be:

transform: translate3d(tx, ty, tz) translateX(tx)

Is it possible to achieve this in CSS without overwriting the current style? My project uses Angular, so should I make changes in the component code? Any guidance on this matter is highly appreciated!

EDIT: I would like to clarify that the translate3d style is already applied to the element by default (not in my own css file, but set automatically by a library). What I am trying to understand is how to retrieve the current style, which is transform: translate3d, and add the translateX style to it as well, resulting in:

transform: translate3d(tx, ty, tz) translateX(tx)

Once again, I want to emphasize that I did not define the translate3d in my css file; it is a style that is automatically set for that specific element due to the library being used. For reference, the library in question is Leaflet for Angular

Answer №1

To create a unique effect, you can utilize the power of relative positioning in CSS by using these properties:

position: relative
left: [tx]

Here is an example to demonstrate how this works:

.my-heading-a,
.my-heading-b {
  position: relative;
  transform: translate3d(40px, 20px, 10px);
}
.my-heading-a {
  left: 0;
}
.my-heading-b {
  left: 80px;
}

<h2 class="my-heading-a">My Heading A</h2>
<h2 class="my-heading-b">My Heading B</h2>

This example now directly modifies the x value of the translate3d property, removing the need for custom variables. It should be noted that the getTransform function used here was mostly copied from a different post on Stack Overflow.

const myEl = document.querySelector(".myElement");
const MOD = 10;

const getTransform = el => {
  var transform = window.getComputedStyle(el, null).getPropertyValue('-webkit-transform');
  var results = transform.match(/matrix(?:(3d)\(-{0,1}\d+(?:, -{0,1}\d+)*(?:, (-{0,1}\d+))(?:, (-{0,1}\d+))(?:, (-{0,1}\d+)), -{0,1}\d+\)|\(-{0,1}\d+(?:, -{0,1}\d+)*(?:, (-{0,1}\d+))(?:, (-{0,1}\d+))\))/);

  if (!results) return [0, 0, 0];
  if (results[1] == '3d') return results.slice(2, 5);

  results.push(0);
  return results.slice(5, 8);
}

document.querySelector(".button").addEventListener("click", () => {
  const [x, y, z] = getTransform(myEl);
  const newX = parseInt(x, 10) + MOD;
  myEl.style.transform = `translate3d(${newX}px, ${y}, ${z})`;
});

.myElement {
  transform: translate3d(100px, 0, 0);
  display: inline-block;
  padding: 1rem;
  background-color: tomato;
  color: white;
  transition: 0.3s transform;
}

.button {
  position: fixed;
  bottom: 0;
  left: 0;
  right: 0;
  background-color: gray;
  padding: .5rem 0;
  color: white;
  font-size: 1.4rem;
}

<div class="myElement">Test</div>
<button class="button">Move it</button>

Update

If you want to add 10px to the original x translation in the translate3d, this code snippet will achieve that:

/* 200px + 10px = 210px x translation */
transform: translate3d(200px, 0, 0) translateX(10px);

div {
  background-color: red;
  padding: 1rem 2rem;
  display: inline-block;
  transform: translate3d(200px, 0, 0) translateX(10px);
}

<div></div>

Original Answer

Instead of using the pattern below:

transform: translate3d(tx, ty, tz) translateX(tx);

You can set up the translate3d properties with custom properties at the beginning and then update each individual value as needed:

transform: translate3d(var(--tx), var(--ty), var(--tz));

In the provided example, custom properties are updated to move the box downwards and to the right. This approach provides full control over the changes made without overwriting existing styles.

document.querySelector(".button").addEventListener("click", () => {
  const style = document.documentElement.style;
  style.setProperty("--tx", "120%");
  style.setProperty("--ty", "80px");
});

:root {
  --tx: 100%;
  --ty: 40px;
  --tz: 0;
}

.myElement {
  transform: translate3d(var(--tx), var(--ty), var(--tz));
  display: inline-block;
  padding: 1rem;
  background-color: tomato;
  color: white;
  transition: 0.3s transform;
}

.button {
  position: fixed;
  bottom: 0;
  left: 0;
  right: 0;
  background-color: gray;
  padding: .5rem 0;
  color: white;
  font-size: 1.4rem;
}

<div class="myElement">Test</div>
