split article into two columns

Question

Good evening, I’d like to know how I can share the <section> below in two columns so that they are identical and with the texts aligned. On my site the left column is correct but the right one is below and leaving the <section> bigger than it should.

HTML

<section id="section-principal">

                <article id="artigo-principal">

                    <h2>Lorem Ipsum</h2>

                    
                        <div id="esquerda">

                            <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>
                            <p>It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

                        <div id="direita">

                            <p>There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.</p>

            </section>

CSS

article{
    width: 900px;
    background-color: rgb(94, 92, 92);
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.5);
    color: white;
    margin: 20px auto 20px auto;
}

div#esquerda, div#direita{
    width: 100%;
}

div#esquerda{
    width: 50%;
    border-right: 1px white solid;
}

div#direita{
    width: 50%;
    transform: translate(100%, -100%);
}

Answer 1

Your friend is a case that the Float makes much more sense than translate, actually the path you are trying to follow with CSS will only give you trouble after.

I made an option with your own code, but I took the transform: translate and used float, look how it turned out. Everything that was in your CSS that was unnecessary I left there commented.

article {
  width: 900px;
  background-color: rgb(94, 92, 92);
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.5);
  color: white;
  margin: 20px auto 20px auto;
  
  overflow: auto;
}

div#esquerda,
div#direita {
  width: 50%;
  
  float: left;
  box-sizing: border-box;
}

div#esquerda {
  /* width: 50%; */
  border-right: 1px white solid;
}

div#direita {
  /* width: 50%; */
  /* transform: translate(100%, -100%); */
}
