Use the pageBreakBefore property in JavaScript to set the page-break behavior before an element. Use the always property to insert a page break before an element.Note − The changes would be visible while printing or viewing the print preview.ExampleYou can try to run the following code to return the page-break behavior before an element with JavaScript −           Heading 1       This is demo text.       This is demo text.       This if footer text.       Set page-break                      function display() {             document.getElementById("myFooter").style.pageBreakBefore = "always";          }

Use the flexGrow property to set how much the item will grow relative to the rest with JavaScript.ExampleYou can try to run the following code to learn how to work with flexGrow property −                    #box {             border: 1px solid #000000;             width: 250px;             height: 150px;             display: flex;             flex-flow: row wrap;          }          #box div {             flex-grow: 0;             flex-shrink: 1;             flex-basis: 20px;          }                              DIV1          DIV2          DIV3             Using flexGrow property       Set                function display() {             document.getElementById("myID").style.flexGrow = "2";          }          

Use the flexFlow property to set the flexible items to be visible in columns.ExampleYou can try to run the following code to make flexible items display in columns with JavaScript −                    #box {             border: 1px solid #000000;             width: 100px;             height: 150px;             display: flex;             flex-flow: row wrap;          }          #box div {             height: 40px;             width: 40px;          }                                  DIV1          DIV2          DIV3             Using flexDirection property       Set                function display() {             document.getElementById("box").style.flexFlow = "column nowrap";          }
