Bootstrap is a free and open-source UI framework. It was developed using HTML, CSS, and JavaScript, and it provides beautiful and cross-browser compatible UI components e.g., forms, buttons, menus, typography, and many more. Creating radio buttons with Bootstrap 4 is very easy, you have to add the radio input class in your radio buttons.
The first wraps the input within the label. This implicitly associates the label with the input that its labeling, and also increases the hit area to select the radio. The second is to have the input and label be siblings and use the for attribute set to the value of the radio’s id to create the association.
What to use to line up labels in Bootstrap 3?
Since Bootstrap 3you have to use checkbox-inline and radio-inlineclasses on the label. This takes care of vertical alignment.
What are the base styles for radio buttons?
The base styles we’ll include here are the font-size and color. Recall from earlier that the font-size will not yet have an effect on the visual size of the radio input. We’re using an abnormally large font-size just to emphasize the visual changes for purposes of the tutorial demo.
Here you see the three radio buttons, each with the name set to contact and each with a unique value that uniquely identifies that individual radio button within the group. They each also have a unique id, which is used by the element’s for attribute to associate the labels with the radio buttons.
To make a radio button selected by default, you include checked attribute, as shown in this revised version of the previous example: In this case, the first radio button is now selected by default.
How many radio buttons can be selected at the same time?
Only one radio button in a given group can be selected at the same time. Radio buttons are typically rendered as small circles, which are filled or highlighted when selected. The source for this interactive example is stored in a GitHub repository.
