<a> tag onclick is not working properly in my admin dashboard?

Question

i have written many <a> tag with 'onlclick' attribute and it's opening different pages. but whenever i click on it. it's not working properly. click working sometimes on right side or sometimes left side of the text .

Let's understand with this an example :
my a tag with onlclick attribute:

<a onclick="$.sidebar.showCard(event, 8, false)" showcard="my_students" class= "w3-bar-item w3-button">
<i class="fas fa-user-graduate"></i> <span>My Students</span>

</a>

whenever a user click on above link it's shows mystudents page.

and when it's not working then this highlights the last link of sidebar, which is logout..
