I only want use CSS for this.

Can anyone give me a solution for this?

  padding: 10px;
}

  color: #fff;
  grid-row: header;
}

Answer 1

Since you are treating this as a table, where the elements stay in the same row, you can also wrap each row in a DIV with "display" set to "contents." This forms an innocuous parent element that you use for hover, and then style the child elements. (display: contents is not yet supported in Edge, though.)

.table {
  display: grid;
  grid-template-columns: [col-start] auto [col-end];
  grid-template-rows: [header-start] 50px [header-end row-start] auto [row-end];
  grid-auto-rows: auto;
  grid-auto-columns: auto;
  grid-gap: 1px;
  overflow: hidden;
  background: gray;
}

.table .row, .table .heading{
  padding: 10px;
  position: relative;
}

.heading {
  background: navy;
  color: #fff;
  grid-row: header;
}

.row span {
  position: relative;
  z-index: 2;
}

.rowWrapper{
  display: contents;
}

.rowWrapper:hover > div{
  background-color: orange;
}

<div class="table">

        <div class="heading">Title 1</div>
        <div class="heading">Title 2</div>
        <div class="heading">Title 3</div>
        <div class="heading">Title 4</div>
        <div class="heading">Title 5</div>
      
    <div class="rowWrapper">
        <div class="row"><span>Row 1</span></div>
        <div class="row"><span>Row 1</span></div>
        <div class="row"><span>Row 1</span></div>
        <div class="row"><span>Row 1</span></div>
        <div class="row"><span>Row 1</span></div>
    </div>

    <div class="rowWrapper">
        <div class="row"><span>Row 2</span></div>
        <div class="row"><span>Row 2</span></div>
        <div class="row"><span>Row 2</span></div>
        <div class="row"><span>Row 2</span></div>
        <div class="row"><span>Row 2</span></div>
    </div>
      
    <div class="rowWrapper">
        <div class="row"><span>Row 3</span></div>
        <div class="row"><span>Row 3</span></div>
        <div class="row"><span>Row 3</span></div>
        <div class="row"><span>Row 3</span></div>
        <div class="row"><span>Row 3</span></div>
    </div>
    
</div>

Answer 2

Here is a trick using pseudo-element. The idea is to use the element as a background and make it overflow on the left and right so that it will cover all the row. Like that if you hover on any element inside a row you change the color and it's like you changed the color of the whole row.

This trick involve few changes on the markup and also more CSS.

.table {
  display: grid;
  grid-template-columns: [col-start] auto [col-end];
  grid-template-rows: [header-start] 50px [header-end row-start] auto [row-end];
  grid-auto-rows: auto;
  grid-auto-columns: auto;
  grid-gap: 1px;
  overflow: hidden;
  background: gray;
}

.table>* {
  padding: 10px;
  position: relative;
}

.heading {
  background: navy;
  color: #fff;
  grid-row: header;
}

.row span {
  position: relative;
  z-index: 2;
}

.row:before {
  content: "";
  position: absolute;
  top: 0;
  bottom: 0;
  right: -1000%;
  left: -1000%;
  z-index: 1;
}

.row:after {
  content: "";
  position: absolute;
  top: 0;
  bottom: 0;
  right: -1px;
  width: 1px;
  z-index: 2;
  background-color: #fff;
}

.row:nth-child(5n+5)::after {
  bottom: -1px;
  right: 0;
  left: -1000%;
  height: 1px;
  z-index: 3;
  width: auto;
  top: auto;
  background-color: #fff;
}

.row:hover::before {
  background-color: red;
}

<div class="table">
  <div class="heading">Title 1</div>
  <div class="heading">Title 2</div>
  <div class="heading">Title 3</div>
  <div class="heading">Title 4</div>
  <div class="heading">Title 5</div>

  <div class="row"><span>Row 1</span></div>
  <div class="row"><span>Row 1</span></div>
  <div class="row"><span>Row 1</span></div>
  <div class="row"><span>Row 1</span></div>
  <div class="row"><span>Row 1</span></div>

  <div class="row"><span>Row 2</span></div>
  <div class="row"><span>Row 2</span></div>
  <div class="row"><span>Row 2</span></div>
  <div class="row"><span>Row 2</span></div>
  <div class="row"><span>Row 2</span></div>

  <div class="row"><span>Row 3</span></div>
  <div class="row"><span>Row 3</span></div>
  <div class="row"><span>Row 3</span></div>
  <div class="row"><span>Row 3</span></div>
  <div class="row"><span>Row 3</span></div>
</div>
