Analyze the basic idea first. First write the HTML, then load the style, and finally use JS to modify the corresponding DOM, to change the tab and content purposes.
HTML displays all text-related information, so the text-related information on this page is the three titles of the tabs above, as well as the contents of the tabs.
So decided to use<ul> <li>the layout of the title, content using<div>layout. Write the following code:
The style that is shown now is this:
To make the tab style shown, there are several places to note:
1. style settings for the entire tab
2. Style settings for TAB titles
3. Style settings for tab content
4. You can only display the contents of one tab, and the contents of other tabs are hidden.
After writing, the effect will come out.
1, first need to get the tab title and tab content
2, the tab content has three, need to iterate to operate, know which tab and which option content matches.
3, by changing the DOM CSS class name, the current click on the tab display, other hidden.
