The second little trick is related to the use of the icon font. We will be using a data-attribute to display the icons. By setting data-icon=”icon_character” with the according character in the HTML we will just need one CSS attribute selector to style all the icons. Read more about this technique on 24 Ways: Displaying Icons with Fonts and Data- Attributes .

The CSS

For the clearness of the code in this tutorial, I will omit all the vendor prefixes, but you will, of course, find them in the files. Once again, I’m using some pretty advanced CSS3 tricks that might not work in all browsers. Let’s get started.

Styling both forms using CSS3

First, let’s give our two forms some general styling for the container.

#subscribe, #login{ position: absolute; top: 0px; width: 88%; padding: 18px 6% 60px 6%; margin: 0 0 35px 0; background: rgb(247, 247, 247); border: 1px solid rgba(147, 184, 189,0.8); box-shadow: 0pt 2px 5px rgba(105, 108, 109, 0.7), 0px 0px 8px 5px rgba(208, 223, 226, 0.4) inset; border-radius: 5px; } #login{ z-index: 22; }

We’ve added a nice box shadow that’s made of two shadows: an inset one to create the inner blue glow, and an outside shadow. We’ll explain the z-index in a bit.

In the following we will style the header with some background clipping:

/**** general text styling ****/ #wrapper h1{ font-size: 48px; color: rgb(6, 106, 117); padding: 2px 0 10px 0; font-family: "FranchiseRegular","Arial Narrow",Arial,sans-serif; font-weight: bold; text-align: center; padding-bottom: 30px; } /** For the moment only webkit supports the background-clip:text; */ #wrapper h1{ background: -webkit-repeating-linear-gradient(-45deg, rgb(18, 83, 93) , rgb(18, 83, 93) 20px, rgb(64, 111, 118) 20px, rgb(64, 111, 118) 40px, rgb(18, 83, 93) 40px); -webkit-text-fill-color: transparent; -webkit-background-clip: text; } #wrapper h1:after{ content:" "; display:block; width:100%; height:2px; margin-top:10px; background: linear-gradient(left, rgba(147,184,189,0) 0%, rgba(147,184,189,0.8) 20%, rgba(147,184,189,1) 53%, rgba(147,184,189,0.8) 79%, rgba(147,184,189,0) 100%); }

Note that at this moment only webkit browsers support background-clip: text , so we will create a stripped background only for webkit here, and clip it to the text to add the stripes to the H1 title. Since the background-clip: text property currently only works in Webkit browsers, I decided to go only with the webkit prefix. That’s the reason why I split the CSS declaration into two parts, and use a webkit prefixed gradient only. Only using the –webkit- prefix is bad practice, it’s only for demo purpose, and you should never do this on real a website! That’s also where the -webkit-text-fill-color: transparent comes in handy: it enables us to only have a transparent background on the webkit browsers, all the other ones will ignore it and give us the provided text color fallback.

We also created a fading line under the title with the help of the:after pseudo-class. We use a 2px height gradient and fade the background to 0 opacity at both ends.

Now let’s style our inputs and give them a nicer look.

/**** advanced input styling ****/ /* placeholder */ ::-webkit-input-placeholder { color: rgb(190, 188, 188); font-style: italic; } input:-moz-placeholder, textarea:-moz-placeholder{ color: rgb(190, 188, 188); font-style: italic; } input { outline: none; }

First we style the inputs, and remove the outline. But be careful here; the outline helps the user know which input is focused, so if you remove it, you should provide some:active and:focus states for the inputs.

/* all the input except submit and checkbox */ #wrapper input:not(){ width: 92%; margin-top: 4px; padding: 10px 5px 10px 32px; border: 1px solid rgb(178, 178, 178); box-sizing: content-box; border-radius: 3px; box-shadow: 0px 1px 4px 0px rgba(168, 168, 168, 0.6) inset; transition: all 0.2s linear; } #wrapper input:not():active, #wrapper input:not():focus{ border: 1px solid rgba(91, 90, 90, 0.7); background: rgba(238, 236, 240, 0.2); box-shadow: 0px 1px 4px 0px rgba(168, 168, 168, 0.9) inset; }

Here we used the:not pseudo class, to style all inputs, except the checkbox. I provided a:focus and:active state, since I decided to remove the outline.

And now the fun part: the icon font. Since we can’t use:before and:after pseudo classes on inputs, we’ll have to cheat a little bit: we’ll add the icon to the label, and then place it in the input. I’m using the fontomas library which puts together some nice icons. You can rearrange them to set the icon to a specific letter. Remember the data-icon attribute? It’s where you should put the letter. I used data-icon=’u’ for user, ‘e’ for email, ‘p’ for password. Once I chose the letters, I downloaded the font, and used the fontsquirrel font generator to transform it into a @font-face compatible format.

@font-face { font-family: "FontomasCustomRegular"; src: url("fonts/fontomas-webfont.eot"); src: url("fonts/fontomas-webfont.eot?#iefix") format("embedded-opentype"), url("fonts/fontomas-webfont.woff") format("woff"), url("fonts/fontomas-webfont.ttf") format("truetype"), url("fonts/fontomas-webfont.svg#FontomasCustomRegular") format("svg"); font-weight: normal; font-style: normal; } /** the magic icon trick ! **/ :after { content: attr(data-icon); font-family: "FontomasCustomRegular"; color: rgb(106, 159, 171); position: absolute; left: 10px; top: 35px; width: 30px; }

Yeah, that’s it folks, you don’t need to have a class for each icon. We used content: attr(data-icon) to retrieve the letter from the data-icon attribute, so we only have to declare the font, choose a nice color and position it.

Now let’s style the submit button for both forms.

/*styling both submit buttons */ #wrapper p.button input{ width: 30%; cursor: pointer; background: rgb(61, 157, 179); padding: 8px 5px; font-family: "BebasNeueRegular","Arial Narrow",Arial,sans-serif; color: #fff; font-size: 24px; border: 1px solid rgb(28, 108, 122); margin-bottom: 10px; text-shadow: 0 1px 1px rgba(0, 0, 0, 0.5); border-radius: 3px; box-shadow: 0px 1px 6px 4px rgba(0, 0, 0, 0.07) inset, 0px 0px 0px 3px rgb(254, 254, 254), 0px 5px 3px 3px rgb(210, 210, 210); transition: all 0.2s linear; } #wrapper p.button input:hover{ background: rgb(74, 179, 198); } #wrapper p.button input:active, #wrapper p.button input:focus{ background: rgb(40, 137, 154); position: relative; top: 1px; border: 1px solid rgb(12, 76, 87); box-shadow: 0px 1px 6px 4px rgba(0, 0, 0, 0.2) inset; } p.login.button, p.signin.button{ text-align: right; margin: 5px 0; }

The trick here is to use the box-shadow in order to create some extra borders. You can only use one border, but as many box-shadows as you want. We will use the length value to create a “fake” second white border, 3px wide, with no blur.

Then we’ll style the checkbox, nothing very special here:

/* styling the checkbox "keep me logged in"*/ .keeplogin{ margin-top: -5px; } .keeplogin input, .keeplogin label{ display: inline-block; font-size: 12px; font-style: italic; } .keeplogin input#loginkeeping{ margin-right: 5px; } .keeplogin label{ width: 80%; }

We will style the bottom of the form using repeating linear gradients to create a striped background.

P.change_link{ position: absolute; color: rgb(127, 124, 124); left: 0px; height: 20px; width: 440px; padding: 17px 30px 20px 30px; font-size: 16px ; text-align: right; border-top: 1px solid rgb(219, 229, 232); border-radius: 0 0 5px 5px; background: rgb(225, 234, 235); background: repeating-linear-gradient(-45deg, rgb(247, 247, 247) , rgb(247, 247, 247) 15px, rgb(225, 234, 235) 15px, rgb(225, 234, 235) 30px, rgb(247, 247, 247) 30px); } #wrapper p.change_link a { display: inline-block; font-weight: bold; background: rgb(247, 248, 241); padding: 2px 6px; color: rgb(29, 162, 193); margin-left: 10px; text-decoration: none; border-radius: 4px; border: 1px solid rgb(203, 213, 214); transition: all 0.4s linear; } #wrapper p.change_link a:hover { color: rgb(57, 191, 215); background: rgb(247, 247, 247); border: 1px solid rgb(74, 179, 198); } #wrapper p.change_link a:active{ position: relative; top: 1px; }

Now you’ll notice that we’ve got two nice forms, but we really want only one to show at a time. So now is time for some animations!!

Creating the switching animation

The first thing to do is to hide the second form by setting the opacity to 0:

#register{ z-index: 21; opacity: 0; }

Remember that our login form had a z-index of 22? We will give the second form a z-index of 21, to put it “under” the login form.

And now the really good part: switching the forms using the:target pseudo class. What you really have to understand about:target, is that we will use anchors to make the transition. The normal behavior of an anchor link, is to jump to the target in the page. But we don’t want to jump anywhere, we only want to switch the forms. And here comes our trick using the two links at the top of the page. Instead of directly linking to the second form, and risking getting a “jumping” effect, we actually put the two links at the top of the page and give them display: none . This will avoid any page jump. Credit where credit’s due: I found this trick on CSS3 create (in French).

#toregister:target ~ #wrapper #register, #tologin:target ~ #wrapper #login{ z-index: 22; animation-name: fadeInLeft; animation-delay: .1s; }

So this is what happens: when we click on the Join us button, we trigger the #toregister. We then do the animation, by using the sibling selector ~ to find our #register element. We use an animation called fadeInLeft . Since we “hide” the form using zero opacity, we will use an animation that fades in, to make it appear. We’ve also changed the z-index, to make it appear on top of the other form.
The same happens for the other form.

And here is the code for the animation. We are using the CSS3 animation framework from Dan Eden and adapted it for this tutorial.

Animate{ animation-duration: 0.5s; animation-timing-function: ease; animation-fill-mode: both; } @keyframes fadeInLeft { 0% { opacity: 0; transform: translateX(-20px); } 100% { opacity: 1; transform: translateX(0); } }

The form that is “disappearing” will have another animation which will make it fade out to the left:

#toregister:target ~ #wrapper #login, #tologin:target ~ #wrapper #register{ animation-name: fadeOutLeftBig; } @keyframes fadeOutLeft { 0% { opacity: 1; transform: translateX(0); } 100% { opacity: 0; transform: translateX(-20px); } }

You can now use other animations from Dan Eden’s animate.css: just adjust your .animate class and replace the animation names. You will also find some custom animations at the end of the animate-custom.css file.

Well, that’s it folks. I hope you enjoyed the tutorial!

Please note, that in some browsers background-clip: text is not supported. In Internet Explorer 9 the transitions and animations don’t work, so there will be no fancy form switching. In Internet Explorer 8 and below the:target pseudo-class is not supported, so it won’t work at all (you’ll just see the login form).

В данной статье будет описан процесс реализации возможности регистрации и аутентификации пользователей наиболее простейшим образом.

1. Регистрация

Начнём с регистрации. Django "из коробки" предоставляет форму создания пользователя UserCreationForm , которую мы и будет использовать для регистрации. Плюс ко всему, она автоматически делает все необходимые проверки. Например, зарегистрирован ли уже пользователь с данным именем. Построенное на основе данной формы представление будет иметь следующий вид:

From django.views.generic.edit import FormView from django.contrib.auth.forms import UserCreationForm class RegisterFormView(FormView): form_class = UserCreationForm # Ссылка, на которую будет перенаправляться пользователь в случае успешной регистрации. # В данном случае указана ссылка на страницу входа для зарегистрированных пользователей. success_url = "/login/" # Шаблон, который будет использоваться при отображении представления. template_name = "register.html" def form_valid(self, form): # Создаём пользователя, если данные в форму были введены корректно. form.save() # Вызываем метод базового класса return super(RegisterFormView, self).form_valid(form)

Как видно, зарегистрировать пользователя достаточно просто. Теперь необходимо добавить ссылку на представление в urls.py :

From django.conf.urls import patterns, include, url urlpatterns = patterns("", ... url(r"^register/$", views.RegisterFormView.as_view()), ...)

И тег {{ form }} в шаблон register.html :

Таким образом, перейдя на страницу ваш.сайт/register/ можно будет увидеть форму регистрации, которая, если повезёт, даже будет работать. Однако, выглядеть она будет страшновато. Как применить к ней форматирование и стили CSS можно догадаться из статьи или почитав документацию.

2. Аутентификация

Принципы реализации аутентификации абсолютно те же самые, но реализация немного сложнее (за счёт использования некоторых дополнительных функций). Без лишних слов, смотрим на код и читаем комментарии:

# Опять же, спасибо django за готовую форму аутентификации. from django.contrib.auth.forms import AuthenticationForm # Функция для установки сессионного ключа. # По нему django будет определять, выполнил ли вход пользователь. from django.contrib.auth import login class LoginFormView(FormView): form_class = AuthenticationForm # Аналогично регистрации, только используем шаблон аутентификации. template_name = "login.html" # В случае успеха перенаправим на главную. success_url = "/" def form_valid(self, form): # Получаем объект пользователя на основе введённых в форму данных. self.user = form.get_user() # Выполняем аутентификацию пользователя. login(self.request, self.user) return super(LoginFormView, self).form_valid(form)

Осталось, аналогично регистрации, добавить ссылку в urls.py и создать шаблон login.html (кстати говоря, подойдёт и представленный выше шаблон регистрации без каких-либо изменений).

3. Выход

4. Заключение

Скопировав и склеив всё это, можно получить минимальную систему "чтобы работало" с большим потенциалом для улучшения. Например, можно реализовать страницы восстановления и изменения пароля аналогичным образом на основе форм PasswordResetForm и PasswordChangeForm из django.contrib.auth.forms .
