a gantt chart is a handy type of bar chart that is used in project management for showcasing a schedule of tasks. as a front-end web designer or developer, you can make use of gantt charts to manage projects and enhance the productivity within your team. this is where all the remaining actions are going to take place. notice that i’ve set the display property of the class to grid. notice that i used the grid-template-columns property to specify the width and the number of columns in the grid layout. for example, a property of grid-column: 3/9; like the “development” entry, spans a task across the grid from march to august.
ultimately, it resulted into a nice-looking gantt chart, just like the image i showed earlier. with this type of chart, you can manage your web development projects effectively and ensure that everyone is on track toward accomplishing the stipulated objectives. for example, if you are selling composting toilets, you can use gantt charts to showcase the number of sales made over a period of time. there are several other tweaks you can make to gantt charts to suit your specific requirements and project’s goals. learn to code for free. we accomplish this by creating thousands of videos, articles, and interactive coding lessons – all freely available to the public.

gantt chart html guide
therefore, in this article, i will develop the foundation for a gantt chart component whose appearance and functionality you can customize for any use case. i decided to implement the gantt chart as a web component. in the constructor, we first define our rough template as the shadow dom of the element. please note that i have used a so-called constructor function instead of the class keyword to define the class.
in the first step, we have to determine the number of columns of the grid. in the second row, i use the same three divs to keep the vertical alignment. this makes it possible to use the css calc function to dynamically set the width of a job element, as shown in the following listing. we can achieve this with the use of javascript proxy objects: each job is nested in a proxy object, which we provide with a so-called validator.
we will use javascript modules to split the code into separate modules that can be imported and exported, so we’ll need a local http server to run the code. we use this to identify the html element that will be used to create our gantt chart component. for each html element on our page that has a role of “gantt-chart”, we create a gantt chart using the ganttchart constructor function. it returns a css string that we import and add to the html string in htmlcontent.js. we then append this to the ganttchartelement so that it is added to the document dom. we then call the six functions required to create the columns, rows, and task duration elements. we still need to make the task edit and delete functional. we need to add event listeners to listen for a change in the date range so that we can dynamically update the grid.
we then add the day element as a child to the time period element for the given month. if the start cell is found, we call the createtaskdurationel function, which will create the task duration element and add it as a child to the cell at its starting position in the grid. we do this to style the task duration element that is being dragged. we will use this value later to remove the task duration element that was dragged, create a new task duration for the new position on the grid, and to update the task durations. we remove it from the dom and create a new task duration element for the task duration’s new position using the createtaskdurationel function. lastly, we create a task duration element and add it to the grid, if we can find its start position. to make the add task form functional, we will first create a “submit” event listener. we find the largest current task id, and then add one to it to create the id for the new task.
unlike the other chart tutorials, we’ll be making heavy use of javascript to implement various aspects of the chart. you’ll be able to use this basis as a gantt chart template for future projects. nowadays gantt’s techniques are used for way more than warfare; in fact you’ll find them present in most industries.they make it easy to visualize a list of tasks, the dependance of those tasks on one another, and their state of completion. in actual fact, you don’t have to be a manager to use them. most project management platforms use gantt charts as a core part of their offering. take a look at some of the gantt chart templates available right now on envato elements. there are also a number of free and proprietary solutions available out there for building your own gantt charts.
as a result of that minimum width, on small screens the chart won’t shrink beyond that, and a horizontal scrollbar will appear. to better visualize the left and right boundaries of each item, we’ll use their ::before pseudo-element. instead of hardcoding that value, there’s always the option to dynamically calculate it through javascript. later we’ll dynamically set their left position according to the value of their data-duration attribute. note: in the code above, we use the element.offsetleft property to retrieve the left position of an element relative to its parent. plus, we take advantage of the element.offsetwidth property to find the element’s width. we managed to build a fully functional gantt chart.
