`position: fixed` applied to an element breaks the positioning of its content regulated by `display: flex`

I need the .word and the .line elements be fixed to the top of the viewport when the page is scrolled - in the position they initially are, i.e. the line is below the word.

I managed to fix the .word with position: sticky, but faced 2 problems:

  1. when I apply sticky to the .line, it "jumps" above the word, and I don't know how to fix it to the top of the viewport, but force it to stay below the .word element
  2. sticky is initially not the right value - it "shakes" the text when you start scrolling. The correct value is fixed - it works just fine, I'd rather prefer to use it! However, it breaks the position of the .warning class (red font): it should be on the opposite side (horizontally) from the .transcription text, but the fixed value collapses the text from those 2 classes together.

    Here is also the JS Bin with this "situation".

.word {                                  
  position: sticky;
  top: 0;
  z-index: 1;
  background-color: white;
}


.word {
        padding: 1vw 3vw 2% 3vw;
      }

      .word-details {
        display: flex;
        justify-content: space-between;
        align-items: baseline;
      }

      .transcription {
        font-weight: normal;
      }

      .warning {
        color: red;
        margin-left: auto;
      }

      .line {
        border-top: 2px solid #fdb239;
      }

      .meaning {
        list-style-type: none;
        counter-reset: item;
        hyphens: auto;
        font-size: calc(0.7em + 1.5vw);
      }

      .meaning > li {
        position: relative;
      }

      .meaning > li::before {
        content: counter(item);
        counter-increment: item;
        position: absolute;
        top: 0;
        text-align: center;
        margin-left: calc(-0.7em - 2.5vw);          
      }

      .meaning-word {
        margin-top: 50px;
      }

      .sentences {
        list-style-type: none;

        margin-top: 30px;

Solution

  • Hi,

    keeping several elements separate at the top of the page while scrolling can be difficult, so I suggest a simpler solution. This "jumping" of Yours sticky bar is because the initial position of the sticky bar is different than the position setted to sticking it on the page top when scrolling.

    Solution

    1. To avoid your hr line disappearing while scrolling, I would put all the components you want to keep at the top of the page in a container e. g. a div and then make that container sticky.

    2. Second problem is because the default body margin (which is 10px) sets Your sticky bar a little lower at the start. Then we scrolling the page - the body margin has already been overscrolled as well and You set the sticky bar to be absolutely on the top (top: 0;), so it must jump to the top this additional 10px. Fast fix is setting body top margin to 0 and then the position of Your sticky bar is always same on the top of the page.

    Here below is an updated snippet of your code.

    body {
    margin-top: 0;
}

.sticky-container {
    position: sticky;
    top: 0;
    z-index: 1;
    background-color: white;
}

.word {
    padding: 1vw 3vw 2% 3vw;
}

.word-details {
    display: flex;
    justify-content: space-between;
    align-items: baseline;
}

.transcription {
    font-weight: normal;
}

.warning {
    color: red;
    margin-left: auto;
}

.line {
    border-top: 2px solid #fdb239;
}

.meaning {
    list-style-type: none;
    counter-reset: item;
    hyphens: auto;
    font-size: calc(0.7em + 1.5vw);
}

.meaning > li {
    position: relative;
}

.meaning > li::before {
    content: counter(item);
    counter-increment: item;
    position: absolute;
    top: 0;
    text-align: center;
    margin-left: calc(-0.7em - 2.5vw);          
}

.meaning-word {
    margin-top: 50px;
}

.sentences {
    list-style-type: none;
    padding-left: 0;
    font-size: calc(0.7em + 1.5vw);
    margin-top: 30px;                   
}

.sentences > li.sentence-ru {
    margin-top: 15px;                   
}
