We will increase the value by 1 per timeframe - you can increase the value to make the progress run faster.Īnd then, we add the result to the progress bar. Inside the above function, we set the progress interval. In this example, we call the variable loading. Next, we create a variable that store the animation function. First, we store the progress bar element, the progressbar value as well the maximum value, and the timeframe, in Variables. Then, we add the scripts to make the progress bar expand. So, we should also not forget to insert the jQuery, like so. In this example, we will use jQuery to animate the progress bar. We will also display the value number as it is progressing. The idea is, the progress bar will expand from 0 and stop once it reaches the maximum value. Typically, the progress bar expands from left to right as the task progresses. Next, we will see how to animate the progress bar. To conclude, these are currently the entire selectors for styling HTML5 progress bar. Unlike Chrome and Safari, this pseudo-class in Firefox refers to the progress meter/value. Thus, to change the progress bar and the progress value styles in these browsers, we need to add those Webkit pseudo-classes.įirefox also has its special pseudo-class that is ::-moz-progress-bar. In Chrome and Safari, the progress element is translated this way. So, we need some more workaround in these cases. In Chrome and Safari, it will remove the native styles and presentation from the platform and replace it with the Webkit stylesheet, the styles above will not be applied (at least, at the moment). In Firefox, the styles affect the progress bar, while the progress meter / value is not affected. However, each browser handles this a bit differently. In this example, we change the background color, remove the border line, and make it rounded by adding a border radius at half of its height. In the stylesheet, we actually can use the element selector to target and add style rules to element. Now, let’s try styling this progress bar, so it has a consistent or similar look across all platform. Below is how a native progress bar looks in Windows and OSX. Since this is a native progress bar, the presentation is vary dependent on the platform. The progress bar can be added with the progress value is determined with the value, min and max attributes, as follows. 1Īs Internet broadband connections get faster, our internal waiting clocks run on shorter and shorter minutes. Line 16: This line calls the animateProgressBar function with the progress bar element ( progressBar) and a duration of 2000 milliseconds (2 seconds) as arguments.30 Beautiful Progress Bar Designs, Vol. If so, the animation is complete, and the clearInterval function is called to stop the interval from executing further. ![]() Lines 9–13: The code checks if the progress has reached or exceeded 30. This updates the width of the progress bar element, effectively animating its progress. This updates the progress of the animation. Line 6: Inside the callback function, the progress variable is incremented by the increment value. The callback function will be executed repeatedly at the specified interval. This function takes two parameters: a callback function and an interval duration. Line 5: The interval variable is declared and assigned the return value of the setInterval function. This determines the amount by which the progress bar should increment with each interval. ![]() Line 3: The variable increment is calculated by dividing 1 by the duration parameter and multiplying it by 100. This variable will keep track of the current progress of the animation. Line 2: The variable progress initializes with a value of 0. Line 1: The code defines a function called animateProgressBar that takes two parameters: progressBar and duration.
