Image gallery thumbnail size with Bootstrap 4










0














I have a very simple responsive image gallery with 6 thumbnails only. In large and medium devices it shows perfectly. However, in mobile view, the thumbnails become way too small. If I add padding, the side margins "break" and they are no longer aligned. Is there a way to make them a bit bigger without "breaking" the side margins? I've posted images so it's easier to understand.



In the image below you can see that the side margins are aligned, but the thumbnails are too small.



This is what I want to achieve



And below you can see what happens when I add padding. The thumbnails are bigger, but the side margins are no longer aligned.

.container 
max-width: 98%;
margin: 0 auto;


.image-container
background-color: #ffffff;
padding: 10px;


.main-image-container img

.thumbnail-image-container img

          One solution would be adding the same padding to all col-* classes. Bootstrap have padding classes named p-*. Next example added the p-1 classes to main-image-container and thumbnail-image-container elements.






          .container 
          max-width: 98%;
          margin: 0 auto;


          .image-container
          background-color: #ffffff;
          padding: 10px;


          .main-image-container img
          max-width: 100%;
          height: auto;


          .thumbnail-image-container img
          max-width: 100%;
          height: auto;

          <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">

          <div class="container mt-4">
          <div class="row">

          <div class="col-lg-7 image-container">

          <div class="row">
          <div class="col-12 p-1 main-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
          </div>
          </div>

          <div class="row pt-2">
          <div class="col-2 p-1 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
          </div>
          <div class="col-2 p-1 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
          </div>
          <div class="col-2 p-1 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
          </div>
          <div class="col-2 p-1 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
          </div>
          <div class="col-2 p-1 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
          </div>
          <div class="col-2 p-1 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
          </div>
          </div>

          </div>

          </div>
          </div>





          A second solution will be splitting the thumbnails into two rows using the right col-* classes. Like on next example:






          .container 
          max-width: 98%;
          margin: 0 auto;


          .image-container
          background-color: #ffffff;
          padding: 10px;


          .main-image-container img
          max-width: 100%;
          height: auto;


          .thumbnail-image-container img
          max-width: 100%;
          height: auto;

          <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">

          <div class="container mt-4">
          <div class="row">

          <div class="col-lg-7 image-container">

          <div class="row">
          <div class="col-12 main-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
          </div>
          </div>

          <div class="row pt-1">
          <div class="col-4 col-md-2 mt-2 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
          </div>
          <div class="col-4 col-md-2 mt-2 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
          </div>
          <div class="col-4 col-md-2 mt-2 thumbnail-image-container img-fluid">

          <div class="col-4 col-md-2 mt-2 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
          </div>
          <div class="col-4 col-md-2 mt-2 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
          </div>
          <div class="col-4 col-md-2 mt-2 thumbnail-image-container img-fluid">

          </div>

          </div>

            One solution would be adding the same padding to all col-* classes. Bootstrap have padding classes named p-*. Next example added the p-1 classes to main-image-container and thumbnail-image-container elements.






            .container 
            max-width: 98%;
            margin: 0 auto;


            .image-container
            background-color: #ffffff;
            padding: 10px;


            .main-image-container img
            max-width: 100%;
            height: auto;


            .thumbnail-image-container img
            max-width: 100%;
            height: auto;

            <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">

            <div class="container mt-4">
            <div class="row">

            <div class="col-lg-7 image-container">

            <div class="row">
            <div class="col-12 p-1 main-image-container img-fluid">
            <img src="https://placeholdit.co//i/1280x720?&text=Test">
            </div>
            </div>

            <div class="row pt-2">
            <div class="col-2 p-1 thumbnail-image-container img-fluid">

            A second solution will be splitting the thumbnails into two rows using the right col-* classes. Like on next example:

            .main-image-container img
            max-width: 100%;
            height: auto;


            .thumbnail-image-container img
            max-width: 100%;

                One solution would be adding the same padding to all col-* classes. Bootstrap have padding classes named p-*. Next example added the p-1 classes to main-image-container and thumbnail-image-container elements.






                .container 
                max-width: 98%;
                margin: 0 auto;


                .image-container
                background-color: #ffffff;
                padding: 10px;


                .main-image-container img
                max-width: 100%;
                height: auto;


                .thumbnail-image-container img
                max-width: 100%;
                height: auto;

                <div class="container mt-4">

                <div class="col-lg-7 image-container">

                <div class="row">

                A second solution will be splitting the thumbnails into two rows using the right col-* classes. Like on next example:






                .container 
                max-width: 98%;
                margin: 0 auto;


                .image-container
                background-color: #ffffff;
                padding: 10px;


                .main-image-container img
                max-width: 100%;
                height: auto;


                .thumbnail-image-container img
                max-width: 100%;
                height: auto;
